hollow grind

[@davematic1]

A+ on the jig i have been trying to think of a way to insure a consistant grind on some of my projects and that jig you have has given me some ideas. thanx!

[@1lupus]

One of the best grinding vids I have ever seen. I subscribed instantly just on the strength of the one video. Bravo.

[@lmogden1]

GREAT VIDEO I USED TO BE IN THE BELT BUSINESS IN THE UK A SUGGESTION FOR YOU IS PUT A BUCKET OF WATER UNDER THE CONTACT WHEEL THIS REDUCES SPARK DUST ON THE FLOOR, AND MAKE YOUR BELT A WET ONE , YOU ONLY NEED A SPONGE NEAR THE BACK OF THE BELT WITH A SMALL SUPPLY OF WATER ON IT THE BELT LOOKS DRY BUT IS IN FACT DAMP THIS HELPS A LOT WHEN GRINDING KNIFE BLADES

[@yasennikov]

Great video, sir. Nice tutorial on grinding big flat grinds!

[@miniwaern]

Comment to the narrator of this clip: You don't need to yell, my friend!

[@3228000]

FANTASTIC, I hope if you have time you might do a video on buffing and finishing the blade. For example putting that mirror finish on the blade etc. I haven't seen any of that in here, please share more with us.....Thnaks

[@MrReubenHood]

just needed a look at your setup, now I can start hollow grinding my knives :)

[@marvmeyer6659]

I have that same Wilton square wheel grinder.. use it to sharpen my carving tools ..I love it

[@gordonbooco6491]

I have that same Wilton square wheel grinder. How do I get the hollow grind attachment? I need a jig to help keep my grind at the ricaso (Spelling ?) even on both sides. Do you sell that jig or tell me where to get one. ThanksGordon

[@Hellgap50]

I really enjoyed watching you make the fixed blade damascus / mammoth tooth handle knife. I use lots of klingspore yellow belts for finishing handles they would work awesome for tooth. They are a very low priced belt but have a nice stretch to them for working in the slack belt mode. Its one of about 10 different types of belts I use. I get them from jantz but tracey mickley has them too for a great price. Try them out youll like um . kellyw

[@doug2349]

man it must be pretty cool making homemade knifes :)

[@bekanav]

Nice grinding machines. But here in Finland smith uses hammer and anvil to make blades. Then final sharpening is done with wet grinding wheel.

[@gunchag]

Really beautiful grind!

[@MrTarkus007]

very interesting cool i wish i had some of those tools n machineries .........nice work

[@Paracorder]

"... don't wanna get it too hot and work harden that steel... " great job bud

[@aarondickenson7146]

Cool video thanks for the tips !

[@matsonruddell8795]

That jig is awesome

[@COBladesmith80]

@MrRavishraven That one is old school... I don't think you can buy them any more? You can find similar models in any knifemaking supply catologue though... Try "Jantz Supply" or "Texas Knifemaking Supply". Thanks for watching!

[@COBladesmith80]

Thanks for the comment man! As for your question, I don't change the grits on that machine. I only use a 36 grit belt to hog out the material. All finish work afterwards is done by hand on my bader III. I would try just making some marks on the jig assembly to get it back in the same position. Hope this helps ya out!

Great jig for grinding. I will make one for my shop too. :)

[@planecrazyish]

Amazing skills.

[@bone-a-fydecustomknives5610]

If you don't mind, can you tell us where you got your bevel jig attachment??? That thing is AMAZING!!!!!

[@aldogressa6708]

Great video, in the second sander do you eliminate or convex?

[@COBladesmith80]

@gofigurewashington Just sheet copper/brass. You can get it from any knifemakers supply. Check out Jantz supply.

[@BenHayat]

Nice work!

[@scottiblasto]

would love a vid on how you made that jig!

[@COBladesmith80]

@okkrom Tapering the tang is a basic function of balance. I takes weight off the handle, and can give a large knife a better feel. It also offers some aesthetic appeal. Good luck on your knife project! Let me know if you have any more questions!

[@nhvalentine]

I make knives by hand also. I am wondering what the machine is you''re using for the hollow grind. It is VERY nice. Much better than the sander I've been using.

[@BigIronTV]

nice video. I like the hollow grind jig

[@DBowenKnifeWorks]

I Just set this jig up on my bader. How do you change the belts in between grits and set the jig up right where you had it before? And to all of you asking about the yelling.... the machine is very loud.

[@johansmith1011]

Where can i buy the grinding jig?

[@RileyKnifeandTool]

I wonder if this jig would work for flat grinding if you angle your platen?

[@nickloves7279]

Very cool, thanks for sharing the video :O)

[@svelter3504]

I only have a bench grinder what do you think I should do?

[@davidendres7808]

Hey mate loved your video what grade of steel are you using thanks from down under

[@tridneven]

Hi,could you show in closer view this jig?I cant get the way it works.

[@COBladesmith80]

@rjsahadi Thanks for the kind words!! Did you watch any of my other knifemaking vids? I can make just about anything you can dream up! I'll be posting more vids in the future too! Hope to hear back from ya! Later.

@jedirifleman Not to mention his first name was JAMES not JIM. He wasn't just an American hero, he was also a slave trader and a Mexican citizen.

[@zahnklyberg9448]

What direction are you running the belt? I guess the sparks say reverse

[@ChuckRichardsHandmadeKnives]

Very cool. Chuck

[@paultroiani255]

What is the advantage of a flat grind over a hollow grind?

[@UtahClark]

Thanks for the video

[@SteveEilertsenSouthAfrica]

Thank you sir.

[@leloodallasmultipass]

I'm right here, dude.

[@AeroSport103]

Good video Sir.

[@skiboyscuba]

Thanks for sharing

[@mindfreak001009]

what king of material/steel you used for the knife.,any info please?

[@usmcretired2112]

What type machine are you using here? I know it is basically a belt grinder, but it looks like a special type made just for knife work. The jig you are using is the bomb too, what is it, did you make the jig?

[@cdx83]

I'd leave the hollow grind as it is at around 3:30, maybe extend it about a quarter inch up to the spine. The blade appears to be tougher and more shockresistant that way compared to the flat grind you're showing. What's your opinion on that?

[@williamturner6882]

I was told by the man that designed that jig that it will work flat grinding. I haven't tried it though. \

[@COBladesmith80]

@ARCustomKnives You know I never thought of using the platen, but I don't see why it wouldn't work. I just want to hog that material out, so I start with a hollow grind.

[@mikewarren7855]

ok im confused, why hollo grid just to flatten it out. thats kinda pointless

[@giovannifresolone2029]

Mike Warren . Auguri

[@dudefacial]

Mike Warren I was thinking the same

[@paleo4me]

Pretty COOl man! Is your wife or Esteban working the camera? Nice camera work regardless!

[@kylekessler1610]

dang i dont like big knives and that is cool. soo nice i love the sheath

[@kylekessler1610]

hollow grind to make it thin for cutting. who wants a fat knife with an edge?

[@davecarpetcare]

Nice video. What is that machine that you are using to put on the hollow grind? It looks like a high end belt sander. How much are they and where can they be purchased? Thanks for any response.

[@behemothsuperknife]

It appears to be a Wilton. I think it might be called the square wheel. Just look up 2x72" belt sanders. All kinds will come up.

[@zapple8286]

knife looked cooler with the bevel

[@DBowenKnifeWorks]

@COBladesmith80 Wondering if you sell those jigs? I'd be interested in getting a hold of one for my shop.

[@ja001son]

Did you make that jig or purchase it somewhere?

[@josephkousa9605]

You need to wear a mask man!

[@jeancharlesmujor9963]

[@COBladesmith80]

@cdx83 To be honest with you, I hated that project... Another crazy Dan-D design I guess... Thanks for watching. l8r

[@Scogny]

PleSe What is the name of that litle instrument that you have utilized duri g oo:30 of video ? To mark line to each sides of blade

[@TheHairOfElendil]

Sharpie

[@Scogny]

Not the sharpie but what you use to have correct line to mark. But the flat gauge, do you have a link where to buy please? Or the correct name order to search correctly. Thanks

[@tatermorgan6559]

where can i get a grinding jig for my Bador?

[@COBladesmith80]

Pretty sure Jantz sells one.

[@tgrafix]

Great vid stay healthy wear your gloves and goggles

[@hugojoseteixeira3514]

Com uma máquina destas faço uma industria de facas! Aqui no Brasil cutelaria virou passa tempo de rico, para se ter uma destas máquinas em uma oficina de um verdadeiro artesão, aquele que nasceu com o dom, se não for filho de rico, não compra, deve custar uns 5 mil dólares. Outra; por aqui estão cobrando duzentos e tantos dólares por 3 metros desta fita de lixar!!

[@johansmith1011]

Who sells that jig attachment?

[@TheMw2prestige]

Did you just try to screw on the top of a sharpie that pops on?

[@COBladesmith80]

Just found you, my friend; just subscribed. Boo-ee, Bow-ee... Makes no difference in the pronunciation, we all know what/whom you're talking about. A lot of the pronunciation has to do with geographical location, not sexual preference. Great job; great video!

What are you shouting?

[@MrPdante]

technically not a bladesmith,who would use a hammer and anvil to shape steel, blade maker or knifemaker would be more accurate. Anywho, nice video and nice knife.
