Get Hard: Heat Treating a Knife with Charcoal

[@smcockrell]

ive successfully heat treated about 2 dozen knives made from 1095 using a method very similar to this. half of them were done in a homemade bucket forge and the rest from the lid of a stainless steel gas grill that i modified with some fire bricks and refractory cement. i can give a few pointers that might save some people from making bad decisions. Mr. Sorrells covered just about everything here, but i would definitely recommend giving yourself plenty of room in (or on) whatever surface your using. for example in my little bucket forge it was just too small and the bottom was way hotter than the top so i ruined a few knives because the tips got so hot they melted. secondly, regular charcoal works just fine if you cant find the lump or whatever. actually i prefer it because the natural stuff sends up huge amounts of embers that can land on something and easily catch it on fire without you knowing. the briquettes get plenty hot to heat treat simple high carbon steel. but the hairdryer is a MUST. it will not get nearly hot enough without it. ive used hair dryers as well as the little pumps that come with some air mattresses. also, hes very correct about the hardness once you quench it. be very, very careful with it until it is fully tempered!!! i cannot stress this enough because i have accidentally dropped two knifes on my way to the temper oven that shattered. if you get warps or anything else, then heat it back up before you start messing around with it because it will most likely break if you dont. also, its a good idea to inspect the blade thoroughly before heat treating because if it has any warps or flaws already, then its very probable that it will cause some serious damage during the quench. ive had warps, splits, breaks, cracks. as soon as you dunk it in the oil be very still and listen for just a moment. if you hear something that sounds like TING!! then you blew it. if you hear nothing and feel nothing, then chances are you probably didnt ruin it. when im using very thin steel i will only do a basic grind on the blade before treating it because the thinner it is the bigger chance it has to mess up during this stage. with thicker steel you dont have to worry so much about cracking or breaking, but depending on the size you can still get some serious warps. also, always do the file test!!!! there is nothing worse than going through the whole process of making the knife, heat treating, putting on handle scales, profiling, fit and finish, sharpening, etc. only to have the edge completely roll over the first time you use it because it wasnt hardened like you thought it was. so always test it!! if you test it immediately after quenching it and it isnt hard, then you can just do it again until you get it right. but if you wait until youre completely finished with it then you dont have very many options at that point (other than maybe using a torch to do a differential hardening). for tempering i just use my toaster oven. he mentioned the amount of scale on the blade after heat treating and that is something that you need to consider beforehand. dont waste time getting the blade perfect before heat treating it because you will need to grind off the scale. so if you spend the time to get a great satin finish on it with perfect bevels, then youre probably going to be disappointed once you pull the blade out of the oil. hope this saves at least one future blade.

[@Boz1211111]

Thanks, i have 1.5 mm thick steel with shaped bevels (so ultra thin) is it sure im going to be disapointed? I tried once and blade cracked and warped, but it was 1.2 mm china steel

[@ericnash7805]

Walter, I recently started watching your videos in a seemingly religious way. You are doing something that no other is at the moment. You are actually educating us beginners with our common man tools, and giving us a rough taste of the theory involved. and your whit makes it entertaining. Thank you very much, and please keep making these videos.

[@ThrowingItAway]

The forge that I've used for years uses a cheapo hair dryer that I found for 10$ at Walmart. With a few fire bricks, a stainless box and a length of black steel pipe, I built my forge for roughly 30$ over a weekend. The Charcoal forge is by far the simplest forge to build and obtain all the parts for.

[@thesteelwolf5230]

bro you show difficult things as easy as a breeze... you are the real pro of this job. Admirations, kudos and all due respect and greetings from Alanya-Turkey :)

[@tooterr101oldgeezer4]

It's really cool to see someone who has all the equipment to make knives and swords to make a video showing others how to do It the hard economical way for others who do not have the equipment you have. thank you very much

[@allymariachi9230]

today I actually welded a small billet about 2 inches long,1 in wide,3 inches thick using only charcoal and bellows in a brake drum forge my first time,I also heat treat katana blades up to 34 inches long using only charcoal and bellows for air.I live in Tanzania,ur tips have been of much use Walter Sorrels thanks for sharing

[@stevenvanrensburg2938]

Thank you Mr Sorrells for taking the time to do these videos, they are very informative and helpful.

[@timothypadilla8910]

Walter, thanks for taking the time to educate those of us who want to hobby build without spending thousands on tools we won't use enough to justify the $$$. Any chance of you doing a karambit in the future?

[@lazarusknight2084]

+Walter Sorrells Hi Walter i see you've made a few Japanese swords, have you ever considered making a European longsword or maybe a Roman gladius?

[@timothypadilla8910]

+Autistic Fingoloid maybe we study Kali and want to learn how to forge and grind our own custom weaponry. Next time keep your comments on the same intelligence level as Walters teaching. Thanks!

[@gomega5646]

+Walter Sorrells I'm actually working on a low tech karambit right now so it would be especially awesome to see how bad I'm screwing it up.

[@nunyabisnass1141]

I'm making a shake out of a leaf spring using a similar method, but instead of an open pit, I'm using a discarded oil barrel. It works better than one may think for getting the steel up to temp...and you can tune the vent holes at the bottom to draw a vortex of air, to get it really hot, and cut slots at different heights from the coals to get a rough temperature difference. Its a good method for those without the proper equipment.

[@haniadel157]

I want to THANK you so much for all the information that you gave us for free.. I'm from Egypt so that is how far your knowledge went or maybe way far than that i hope.. anyway i watched almost every single video you made and they all are very useful and straight to the point.. thanks for that and for more to come, Have a good day sir

[@jimkeith3579]

Walter, I wish that you had done this one last week I just did a blade yesterday in a similar way, had to do it 3 times to get it all treated, first 2 times I did not get the tip on a machete hot enough and it was soft, I ended up using charcoal and some coal that I had in a trench with a hair dryer taped to a pipe with holes drilled in the top side placed in the bottom of it to get enough heat to get the whole blade up to temp :) thanks for the great information

[@joshuabailey5239]

Awesome, Thank you Mr. Sorrells. I think I have a pretty comprehensive guide to start my own bladecraft. I appreciate your knowledge and expertise, and never before have I had such confidence in crafting my own steel.

[@krustysurfer]

Thank you Walter, sustainable, simple and worthwhile. We use our rocket stove style heater, wood fired, 45 min to glowing same color as embers(orange) quenching in cold alkaline water for best results. Water is super infused Borax and Epsom salts best result when solution near freezing. Wonderful hardness. Charcoal is old world and ok by me. Thank you and aloha

[@KinuGrove]

Thank you for doing a basic video like this in 2015 it's still awesome to learn this stuff !!

[@censusgary]

If you don’t have a hair dryer, you can use a bellows. If you don’t have a bellows, you can use a large fan (the non-electric kind you wave with your hand). If you don’t have a fan, you can get several sturdy friends to blow through tubes (hollow reeds, for example). If you don’t have friends (after you roped them into your last project), get to work making a bellows.

[@NotSoDumb]

She bought me a beautiful set of bellows for Xmas. Can't tell you how much I love it.

[@MrWolfman423]

Mr Walter, thanks for all the videos ,I'M trying to be a knifemaker,and your videos helpes me everytime, now making my beltgrinder and forge,Thanks again from Rio Grande Tierra del fuego Argentina

[@foreverdeployed]

Sir, I just wanted to say thanks for making the videos! I have watched several and you are an excellent teacher! Keep up the good work!

[@colsoncustoms8994]

Another way to temper the blade with a fire is to heat another piece of metal and lay the spine of the blade on it. The heat transfers through the spine and should leave the edge harder.

[@shanek6582]

I knew a guy that had an big antique bar of copper with a handle on it and he said it was a tool designed for tempering like that.

[@diskordianer]

+Colson Customs Thats also the way I learned it at a knife maker (in a 2 days workshop). I also can imagine its more evenly heatet that way and its much easier to see the actual color of the blade while heating it.

[@diamondflaw]

+Colson Customs I can't post the link to it apparently, but if you search for "Blade_Forger.wmv www.taliesinpewter.co.uk" and go to about 8:30 it shows this beautifully. Great video to watch if you've got a little time.

[@colsoncustoms8994]

diamondflaw That's a neat video.

[@hanzfranz5795]

the video your talking about is really neat. The knife he made at 12:21 is pretty awesome, i want to make one.

[@TheWtfnonamez]

I find all the hair dryer jokes hilarious... I recently got one and found it to be one of the most useful tools I own. As long as you are careful not to overheat, you can use it for a thousand tasks: Making sure washed kit is totally dry before stowing it in your pack, warming up the inside of your boots when you've treated them, softening Kydex to reshape a sheath..... its almost embarrassing how useful a hairdryer is.

[@eviesanimations8262]

You have the best teaching videos I seen.

[@AriesArriesgado]

This is what Im looking for. Cause I don't have much equipment and an oven to use. Ty for this video.

[@knownaigm]

You really do have that natural knack for teaching. Thank you so much for your videos. The 3 videos I've watched so far answered so many questions I had before trying my hand at making a blade. Invaluable info here. Will definitely be hitting your patreon as a thank you!

[@michaelsanchez8519]

Great video, sir. I've been watching different video on how to learn tempuring, heat treating, quenching, the basics. This video is hands down the the easiest to understand and base knowledge upon. Everything that I wanted to know was found on this video. left a like for ya ;D. I enjoy how much you explain things in a easy but progressive manner. You kept A LOT of the filler out, which as a viewer, bugs the hell out of me. I will be subscribing for sure 👍🗡

Hey Walter, is that a new shirt? Ha ha ha! Great videos sir!

[@ernestuy7128]

i used a pit forge, dug into the ground with a shopvac blowing air into the bottom through a vent tunnel. I was only using wood, but I threw a bunch in there and the fire was ROARING out the top. I didn't know it at the time, but the fire was hot enough to melt the tip of my blade and it turned bright yellow hot. long story short, My knife is now about two inches shorter. I might just restart the blade, but do it more patiently this time.

[@jcs6347]

Thanks Walter! I learn something from you every time because you explain your actions, example: ..Swirl the blade around in the oil to dissipate heart faster... That is why I subscribed; Go Clemson!!!

I waited for the video and it was good that I waited thank you Walter for these great video's. You help me very much.

[@BernieFromTheInternet]

For anyone wondering if you have a medium carbon steel (like a non name brand file) you must simply quench it in water or ice water if its a low/med steel like a railroad spike or something about .3-.4 carbon and move it around so a steam jacket doesn't form, this will work with home depot weld steel, but it wont be hard or tough, it will just be a bit springier than usual

[@redangrybird7564]

How did it go?

[@earlelzy9975]

Hi Walter, I'm a new knife maker. Got into it about 2 months ago. I am a lover of knives. I have a small man cave/workshop which affords me enough space for the equipment I need to get started. I have a couple of books and have enjoyed watching knifemakers on youtube. My question is, can I get a decent knife from a 1x30 belt sander? Question two, freehand or jig?

[@paultroiani255]

You have an understanding wife.. did you promise a new hair dryer?

[@lawrenceb4954]

I was thinking that part of the video should of came with a safety warning.

[@roadchewerpe5759]

Hey, I mean, if it was for getting hard, than whatever!

[@kaizoebara]

Another traditional way to temper the blade is to heat up a big chunk of metal in the fire and temper the blade with that more direct heat source. As you said: put the blade on spine first and let the heat reach the edge until straw colored.

[@warlordzephyr]

I did actually get the temperature up with charcoal briquettes like Sorrells says may work, but then when I switched to hardwood charcoal without realising they weren't the same the difference was significant. There must have been something like a 200 degree difference, and less ash.

[@vermesius1032]

Walter video was great! this was how I was planning on heating my first knife.

[@je3108]

I did some blacksmithing and heat threading witch a forge made out brake drum and wood used as fuel

[@daddydoc1115]

you can use the typical backyard briquettes but you must make a more enclosed furnace, preferably something with a lid to retain the heat. try making a forge from fire bricks or use grant Thompsons video on the mini metal foundry and use that as a forge, i use it and it works fine

[@allymariachi9230]

[@ginoasci]

how do I put somewhat of a hard edge on a knife with a blow torch, canola oil and a toaster oven? heat the metal until it’s red hot, stick it in the oil, wait til it cools, then put it in the toaster at 425 for an hour, then shine it and sharpen it. will that work ok? do i have that right? is it good enough for a cheese knife? i just want to make a few knives for myself and family, with somewhat of a hardened edge so it will stay sharp for a while. i’ll make these knives with old carbide saw blades or some steel hanging around in my shed. thank you in advance for your response :)

[@th_blck_knght]

Man I would love it, and probably a lot of others too, if you would do that video on heat treating theory. Especially if you talked about normalizing and annealing too. Those are the kind of subjects that get all muddied up in schientific text that a normal guy like me has a bit of trouble with getting their head around.

[@neilyakuza6595]

Great videos Walter.

I noticed you are wearing the purple filters on the respirator. Are those the full cross-spectrum gas filters with particulate filters built in? They are basically the civilian equivalent of a military NBC filter right? May I ask why you chose them?

[@orangecheez12]

Hey I have some tips for charcoal heat treating ! First, I've melted 1084 with this method , but I was useing a shop vac for my air supply , I eventually figured out that most shop vacs are TOO POWERFUL! mine made mire spit and burn away so quick so fast I didn't have time to refuel it . But I did melt 1.5 inches off the tip of one of my blades .

[@shanek6582]

Is there any chance you'll ever do a video for us on clay tempering? What mixture, and how to? Also, how, or did the Japanese sword makers temper their swords after the quench? That's something I've never heard about or seen in a video of a quench, thank you Walter.

[@WalterSorrellsBlades]

+Shane K I've got two videos on the whole clay quenching subject (one on forging generally, and the other on hamons specifically) available on my web site www.waltersorrellsblades.com. As far asJapanese sword makers tempering their swords, it's actually typically done somewhat like I do it here -- in other words it's a fairly rapid treatment that might be more what modern metallurgists would call stress relief than the sort of hour-in-an-oven approach that's more typical of modern edge tool makers.

[@generalsongs2495]

I overheated my moms hair dryer but then I tried using an electric fan and it worked! idk if it will make the steel reach white hot but it get the job done

[@juliansosa2889]

Can you use another piece of steel at a higer temperature to heat the blade in a more accurate way to temper?

[@Manarinni]

Awesome video once again, Walter. I don't know if that is a recurrent question but, would you mind putting annotations regarding the temperature in degrees Celsius (we use ISU here in Brazil)? Sometimes is hard to keep focus on the video when I have to convert every temperature mentioned. Thanks a lot!

[@jonduffer4340]

As always great post - Love your sense of humor!!! I suspect there is some kind of character under there!

My first forge was just a pit dug in the ground and a hairdryer...I've made a Japanese box bellows now.

[@elm_experience]

Hi! Looking for some tips of doing HT on 5160 steel, and I have sort of found reading alot that you can get away heating to 1500F and quench in pre-heated canola oil (about 130F). Then I see some temper 2 or even 3 times at 375-400F. Novice here, its again just figures that seems to be common.

[@andregross7420]

Why do you use water on your anvil? Does the hot metal produce a layer of steam, that insulates the hot metal from the (relatively) cold anvil?

[@VT-mw2zb]

+Andre Gross I believe it's a Japanese forging technique to remove the scales that forms as you hammer the piece.

[@andregross7420]

I had actually researched it after posting that. You are correct, and it also helps purify the surface of the steel. Thanks!

[@pascaljohns4242]

It is to blast off the scale

[@Zippr123]

How much/can/should i grind the edge of teh knife before i harden it? I've only done one knife, from an old file. It cracked in several places across the edge and it bent as well. Sure, i did alot of mistakes/didnt lry know. I probably hade to high temp, I quenched it in water. But I think my main problem was that I grinded it to much/it was quite thin. (I thought it would be smart to grind it as much as possible before it would get hard). How much griding work should you do before you treat it?

[@shane-zt9ix]

Walter i have a thermos i wanna put my parks 50 in and use it.. it has a lid and a 4 inch opening.. the can is hollow but it says vacuum sealed.. will that work when it gets hot?. Should I drill a whole on the outside of the canister?.. worried it will expand and explode. My thought is if i poke a hole in the outside of the can, the air inside will release at will.. thoughts plz.. this is a 1gal ozark reail 30 dollars 10.25 dip depth.

[@AerodynamicBrick]

do you think you can show how to make a decent quality small forge to work with crucible steels?

[@cant_standya]

Will this work as well with 1095 high carbon steel?

[@TheMarlough]

First off, Walter, i love your videos. Im also getting confused. I was going to start using O1 tool steel, but read a lot of people saying 1084 is much easier to heat treat at home, and best to leave the 01 to professionals for heat treating. You say both steels use the same method. Anyone care to chime in? Id like to use the 01 over the 1084, but unsure if i can without an electrically controlled kiln.

[@cubaniton74]

Thank you for all the information in the video, and for the list of High Carbon Steel online providers @ 3:22

[@maceinyourface1]

Great video Walter ,but I have a few questions.How thick the edge of the blade must be before hardening and before tempering.Lets say if I harden the knife with the thickness of the edge of the blade of around 1 mm after that should I just clear the blade to be able to see the colors and temper the blade with the edge of 1 mm or should I make the edge thicker and then temper the knife.I have only files and angle grinder as tools and I am worried if I temper and harden the knife with 1 mm thickness of the edge of the blade it will be verry hard to make the edge thicker with just files and if I use the angle grinder to make the edge thicker I am worried I will destroy the colors that are formed after tempering since the work with the angle grinder will produce a lot of heat on the blade.Or should i harden the knife and then make the edge thicker with the angle grinder and then temper the knife ?I don't know what to do.

[@facundovillarroel5604]

Walter, where I live there aren't a lot of different kinds of steels to choose from... What I got is 420 stainless steel. I've already made my first knife and """""heat treated""""" it and I know that I failed on it... I've looked up for and found that it CAN be heat treated (around 1000 Cº). My question is, can i reach that temperature and successfully heat treat 420 steel using charcoal? Hope you can get back to me with some help! Thanks!

[@gustavjanson9682]

Usually when you temper a simple carbon steel knife, you put it in an oven at 400 for about 2 hours... with this technique, is the blade tempered once it has reached that yellow colour? Or do you need to hold it at that temperature for a certain amount of time?

[@damionlowther78]

I've only heat treated a few knives but I've been doing it with the spine down and the edge and tip just outside the main heat. I am just curious if there may be something wrong with doing it this way that I am just not picking up on. In my mind it makes it easier to control the temperature and lowers the risk that I will burn or overheat them.

[@lucan73630]

Love your channel Walter great content!

[@82delta]

+Walter Sorrells Which steel would you choose (only using the simple method shown here) as a hard use knife steel with 5" blade 1/4" thick flat ground and full tang 5 1/2" handle, (pretty much a K-Bar style but full tang) ...1075 or 5160?

[@Nik.ff.]

idk what kind of steel I used but once I've heat treated is 450 degrees for an hour fine for most size knives or do I need to change it to a certain time/temp. Also are there any health hazards with doing it in an oven used for cooking because that's the only oven I have.

[@TheGrenadier97]

Amazing video.

[@TheMrMoggy]

have you tried using aluminium to protect the edge and as a temperature guide during heat treating? aluminium melts at the same temperature as the optimum heat treating temp of O2 steel (816˚C). I'm thinking of trying out a tester but was wondering at any disadvantages or possible metallurgical contamination from using aluminium this way?

[@hamechi836]

hi i need guidance, i heat treat some metal that have told to me is high carbon steel, with charcoal, quench with water and oil but i could not harden it, i think maybe the steel that i used was not high carbon steel, then i quench a file with charcoal and oil(first temper for get soft and shape the blade), but again it don't get hard as i expect, i temper to non magnetic and then quench, but it happen to fast reaching to non magnetic temperature, you think that is the reason why my blade don't get hard correct? maybe i must temper it more?

[@alvaroflorestheflores4692]

wow you rock! just love your info, videos, you have helped me learn many things, Thank You

[@MrMattrix1]

I have just subscribed to your channel and really enjoy your videos. you have probably covered this in one of your other videos but I haven't got round to watching them all yet.. so my question is would you drill all the holes for your handle scales before hardening and tempering the blade, I am looking into making myself a knife using the older methods (cheaper) methods and need all the help i can get as I have no experience. thanks for your time & tips

[@tahoe829]

Excellent video thanks Walter :)

[@1forge2rulethemall88]

If you don't know what type of steel you have how do you harden it? I used an old spike and I cooled it with water but it's my first knife so I don't know how to harden it (a file still marks it so it's not very hard)

[@ryanharrison9760]

Mr. Sorrells. I would like to thank you for a amazing channel. I am going to attempt my first blade using a 10 inch saw blade for material. The question I have is after I have obtained the desired shape and bevels do I need to harden and tempur this kind of steel? I apologize for my ignorance, but I would like to give this a shot. Thank you again Walter. Ryan In Edmonton Alberta, Canada.

[@polishavenger1]

+Ryan Harrison Do you know for certain what steel the saw blade was made from, Ryan?

[@ryanharrison9760]

No. It is a Freud 60 tooth blade. Jeez I should research that. Oh brother.

[@polishavenger1]

+Ryan Harrison My advice (dunno what Walter's would be) would be to steer clear of unknowns IF you're looking to make a high quality product, Ryan. If a saw blade has carbide teeth, the steel in which it is mounted doesn't necessarily have to be high quality, high carbon or anything with properties suited to make a knife blade. If you have the time to do heat treating experiments with older unknown steels, then go for it....just remember that you may be wasting a lot of time for a very disappointing result. Of course, a bad day knifemaking beats a good day housecleaning, right?

[@ryanharrison9760]

thank you for the advice. I'm really not sure about the steel. but I have some other pieces in my shop that I can play around with as well. I was hoping that the steel used for the blade itself would be decent. I've seen video of people using saw blades that's were I got the idea. but in the same respect I don't want to be disappointeded. really appreciate your help.

[@polishavenger1]

+Ryan Harrison You're very welcome. If you go the used table saw blade route, you'll get your best results from OLD, non carbide tipped blades. Get the oldest, nastiest, rustiest blade you can find (1960's vintage or earlier)....that will increase your chances of getting a decent, workable material. Good luck, have fun and be as safe as you can.

hey Walter, love your videos. But curious, how bout using the same method in this video, but instead of hard wood charcoal.... use just a normal wood camp fire? Can the correct temperatures be achieved this way?

[@WalterSorrellsBlades]

+Vox Populi I would imagine if you drove the fire hard enough, cut up the wood into fairly small pieces and some other things that you could get there. But it would be a lot harder than doing it with charcoal.

[@voxpopuli905]

Walter Sorrells I figured this much. I think you have the best videos, and source of information when it comes to making knives, and i think your attention to detail is top shelf, and hope i can get my work to that level as well. Not sure how familiar you are with Schrade schf12 or 11. They are china made production knives , but i love the design of those two. In the hands of someone like yourself that design would be pretty cool. I have hoped for a while to see a video of yours making something like that. Just a hopeful idea of mine. Thank you Mr Sorrells
