K390, My Favourite Steel - Dull to Sharp in 5 Minutes

[@thechugdude]

Sorry to hear about Lemon. We had a cat pass away suddenly as well. Her mouth was bothering her, took her to the vet, diagnosed with cancer, and was around for about 2-3 more weeks. It sucks when you expect them to be around a lot longer.

[@petedavidson712]

My condolences to you and your family, rest easy Lemon.

[@Judgement_Kazzy]

RIP Lemon. Unfortunately kidney failure is a huge problem with cats. Idk if hes part british shorthair, but i have one of those pudgy grey cats, and he's thankfully been very long lived. 18 years old and still in good health.

[@Mr.9x19mm]

Condolences for the loss of Lemon.. Enjoying this series!

[@waylonwade1203]

Lemon was lucky to be a part of your family. Condolences to you and your family

[@Cid_1]

So sorry about the loss of your Cat. I'm scared I have to put down my cat soon as well. She is now totally blind, but finds her way to the litter box the food up and down stairs jumps up and down from the sofa and she is 20 years old. So we are waiting to see if she gets any worse, but the bloodwork was fine. And we have monthly checkups with the vet. So fingers crossed she makes it through the summer at least.

[@Knivess0]

Hope she lives at least another year!

[@beyproctor7673]

I love these dull to sharp videos because it should shame people into learning to sharpen! With the right stone it only takes minutes to get super steel shaving sharp. Maybe double that if you want to polish it.

[@Aerzon1v1]

Once the bevel is set. Even just dropping K390 a few degrees from it's factory edge would take a while on stones, unless you're skilled and have a 140 grit Atoma or XXC Dmt plate.

[@chasetoncain]

i’m so sorry for your loss!! lemon will be missed that’s really rough to go through no matter what. i lost my best buddy mushu almost 8 years ago now and i still can’t really talk about him without tearing tbh. the videos are always great thanks for the updates

[@JoeyKnifeInnovations]

Really sorry about youre cat Lemon who passed away.

[@CNYKnifeNut]

Every time i sharpen my k390 police (which isnt very often) i also take the primary bevels to the stones. It cleans up the rust and keeps the BTE thickness in check.

[@Drankorgels]

This gave me the confidence to finally start sharpening my Stretch 2 in K390 and it was waaaayyy easier than I thought. Just easy work on a Naniwa pro 1000 and a strop and the thing is just scary sharp again.

[@CedricAda]

ooh naniwa, my next destination i believe

[@Drankorgels]

@@CedricAda Great stuff, but I can whole heatedly recommend Shapton Pro too. I got the 320, 2000 and 5000 and they are fantastic. Great prices.

[@realkoly]

Sorry about lemon passing, we had to put down our British short hair at about 17 y/o, she was having big problems with her lungs and heart etc. We can only try to find peace in knowing that our pets are now free from pain and suffering

[@dmelfa1]

So sorry to hear about Lemon, may he Rest In Peace 💐🐈

[@tylerwilliams2272]

That line about pets lifespans passing before our eyes hit home Pete. Came for the knife content, left questioning the futility of life.

[@BrentonCarr]

First! Poor Lemon... K390 is such a great steel to use. I find it easy to sharpen for such a great edge retention steel.

[@Jackass_of_DOOM]

Agreed. As a novice to high performance steels, I was amazed at the fact I was able to get a usable edge (comfortably shaving, cleanly slicing paper) with just the worksharp field sharpener. Great stuff this steel is, gets and stays far sharper than I will ever need for my daily use, and I don't find it much harder than s30v to sharpen, with a much better return on investment in terms of effort sharpening vs edge retention. Also rest in peace to Lemon, an OG of the channel.

[@Surago]

I did not expect to hear about your cat. Omg I'm literally devastated. 😢

[@chrisf572]

So sorry for the loss of Lemon. I’ve recently gotten some k390 in the form of an endela. I like it quite a bit.

[@TundraMMV]

I was very sorry to hear of lemon's passing. I'm sure she had a great life with her family !!

[@petedavidson712]

I love my police k390, best folding knife I own. I tarted mine up with carbon fibre scales, titanium screws, pocket clip, and a wave opener. Does everything the smaller knives do plus some!

[@stevestory8483]

Sorry for your loss 😢

[@hificat101]

So sorryvto hear about your loss of Lemon. Losing a pet always takes a chunk out of me. On an unrelated note, this is the first one of these videos I noticed how that sharpener works and how you set the angle on the end. They should make a premium one with Venev or similar stones.

[@Cid_1]

k390 is my favorite steel as well. Super great performing steel, you can get it on pretty affordable models like the Stretch 2 and so on. Fairly easy to maintain. I would love to see Spyderco do some Rex 54 Mules and sprint runs. Considering Spyderco has done so many Rex steel, I think Rex 54 should be explored next. It got 1% more vanadium compared to Rex 45, and looks really promising from what's described on the Crucible page

[@riverrunner23]

Sorry for your loss of Ms. Lemon. It's always rough when they leave us, R.I.P.,, Lemon. I do love rhe K390 line.

[@DuhYaThink]

Great too see Bricky 🤙🏻RIP Lemon. 😢

[@dionysus6892]

My condolences on Lemon. K390's an awesome steel, you convinced me to get a Stretch 2 and I love it

[@EDCandLace]

K390 is such a easy to sharpen steel for the amount of wear resistance it has.. truly a lovely steel to deal with.

[@tombrown4683]

I also have a K390 Police 4. Pretty impressive considering the neglect & time constraints. I gotta get one of those Work Sharps. Sorry to hear of Lemon's passing. One of the origional pets of this channel. Condolences to your family.

[@archivist17]

Such bad news about Lemon 😢 Condolences to you and the family. And too poor old Basil, who must wonder where his friends are...

[@achimgeist5185]

K390 is one of my favorite steels. I am a fan of tool steels: A2, Sleipner, 3V, 4V, K490, Vanadis 4 Extra, CruWear, M4, K390 etc.

[@TechZACH16]

I live in a place where if I even think of K390 a blade somewhere rusts. My experience with it was awesome and I wish it weren’t so damp here.

[@powerart1]

It's hard being a knife enthusiast in a tropical environment.

[@TechZACH16]

@@powerart1 There are enough awesome stainless steels that I don't ever feel to bummed about it. Properly heat treated Magnacut has been kind of a godsend for me because I don't feel like I'm sacrificing a ton in the name of not having my knives being rusty. Still - K390 was everything I wanted in a steel. Toothy hard working stuff but salt in the air makes it a no go. I used to have a Spyderco in K390 and I remember having real anxiety about carrying it.

Sorry to hear about Lemon.

[@SinistralCitizen]

I'm shocked k390 got that sharp that fast. Sharpenability is one of the reasons I haven't used my K390 stretch lol. Well now that I know!

[@stevecrawford7814]

Love K 390 and use my Police around the house for everything. Sorry about the kitty. I’ve lived thru many lost pets never gets easy.

So sorry for the loss of all your Furkids. Truly one of the saddest things we as humans must go through if we are to experience the love that these 'kids' give us in return. I'm one who believes that God will reunite us with our Furkids when it's our own time to pass. God Bless all Furkids, one of the greatest Joys and Gifts that God has blessed us with.

[@thaimatt999]

What angle are you sharpening to? I have the hardest time trying to figure out edge geometry when using one of these. Also, sorry about Lemon. Rip

[@CedricAda]

this is a roughly 20 degrees, its hard to say precisely

[@thaimatt999]

@CedricAda thanks a bunch

Sry for your loss. How are you liking the preset angle?

[@fuzzynuttz5092]

I have the seki stuff (delica and stretch 2) and a couple of Golden's (pm2 and pm3) and they all perform very well. However, i think the para 3 may have a scuffed heat treatment because its really chippy compared to the others, but still a good knife nonetheless

[@cruwearisthebest397]

[@mccrimmon574ify]

What degrees are u using on the worksharp

[@desertchild.]

I wonder how long the edge would last after doing a 5-minute sharpening and then doing a rope cutting test afterwards

[@robfahey1349]

I know your working for speed but I think ripping the knife off the edge of the stone like that will eventually round your tip. It doesn't look like it right now but more sharpenings like this and I can see it happening.

[@garyfrombuffalo]

i use that one and the other one which i believe is actually better The Manual Guided Sharpening System

[@feralcruz2093]

RIP Lemon 🍋

[@Bob_Adkins]

I came here to see why it takes so long to sharpen a knife. It usually takes me 20-30 seconds, and maybe a minute for very dull knives.

[@JohnVentarino-ey5ln]

Is it better and easier if I'm a beginner with leaving that sharpener swivel and move back and forth instead of keeping it not move at all.

[@CedricAda]

im really in two minds. my past experience found it a bit uncomfortable at first and hard to overcome muscle memory for. but it really does seem to help the swoop through the blades belly when you do let it rock

OMG Pete please clean your ceramic plate with cotton wall balls in mineral oil (or something). It's as black as my boots mate! The horror! 😱Edit: did this before watching. How might a clean ceramic face have cut down the time? You might have got it sharper if the thing wasn't creampie-ing on previous knives' doings?

[@TimJohnson-x1o]

blows my mind how folks, even folks like this guy who do this for a living still don't understand that hardness has fuck all to do with grindability when comparing steels. 65 hrc 1095 will grind like butter next to 40 hrc k390. Why? Because carbides. How much carbide, what kind of carbide, and what size of carbide. Also sharpening isn't just about grinding away material. it's about forming an apex and removing a burr. guess which makes apex formation easier? higher hardness. Burr removal as well. Harder steels are easier to sharpen than softer steels. They're also usually easier to debur. but like everything else there are caveats to that second point. Certain steels like cobalt high speed steels are notoriously difficult to debur. Also, Your freehand sharpening is dire, man. I can't tell if this like ironic or what. You don't need more minutes. You need to actually learn what the shit you're doing. Anyone with basic skills could do better in 2 minutes.

[@budthecyborg4575]

I feel like he's spending too much time polishing. The best way to learn benchstone sharpening is to ONLY sharpen with 80 grit for a month or so, all of your most productive time sharpening is spent on your most coarse grit, if you can't get an edge with 80 grit then polishing is entirely wasted. My method is just using one medium/coarse diamond plate and then strop. The biggest reason to avoid polishing is when you know there's a 99% chance your knife will go dull from accidental edge damage and not from actually cutting things.

[@joi777]

All good n dandy untill u get som acidic or salty stuff into the pivot and rust hell breaks loose. Thats why I prefer M390 n MagnaCut over K390. Atleast in folders.

[@CedricAda]

oh yeah, I dont even know why its my favorite steel. Objectively magnacut is probably overall better
