Knife Making - Kiritsuke Japan Kitchen Knife

[@yadai54]

I’m not sure working on a pre-hardened piece is the correct way. using that cutting disc especially where the edge would be had changed it’s hardening values probably for sure. Working on a soft metal to begin with is 1, less machinery wear and 2, twice as fast shaping results, and then hardening to actually achieve that hardening value was shown on the blade. Beautiful work of art!!!

[@leandromonteiro8613]

Yeah, probably the hardening of the blade is a totally mess... But for some photos, it's very good

[@ThaiPham-rq5ko]

Thought is not a pre-hardened steel. Look at the steel plate!

[@yadai54]

Actually, 58 hrc is pretty high and the blade being heated by that belt grinder and the disc might as well compensate the tempering process, though still, lots of unnecessary wear for his machines 🤷‍♂️:)

[@adamli7168]

Thai Pham it says 58 hrc ，how ever this knife had no forge or heat treatment

[@adamli7168]

Neriya Yadai 58 is really soft for kitchen knife 😢

[@mndlessdrwer]

It is beautiful precisely because it is simple. It is the elegance of simplicity that makes every detail stand out.

[@Ms.Nightshade]

I have never seen such an amazing degree of precision with an Angle Grinder!

[@OsmanAli-wr8kg]

go check out Freerk Wieringa. He is so scary and precise with an angle grinder.

[@jacklawford6452]

you aren’t supposed to use it on the flat face tho :/

[@dannyseo6759]

I'm lucky to have all eleven of my fingers left.

В десятки раз приятнее смотреть такие качественные ролики, если их автор - соотечественник! У Вас нереально крутые изделия! Смотрю ваши видео по несколько раз. Так держать!

[@Белогоръ]

Нож ладный получился! А без бряканья музыки,с Реальным Звуком видео просто супер,давно с таким удовольствием не смотрел!

[@nesiler9184]

Так и есть!!! Почти весь канал такой!

[@brittanysisk7518]

I love the blade shape

[@easyki84]

Nice piece of art. Btw: The continues grain in the handle. This kind of details are what good knife makers sets apart from the others.

[@pknlpr]

That has to be one of the most beautiful knifes I seen made. Would love to own one you make.

[@tomhangs2008]

Why i spend all day watching knifemaking videos?

[@ЛеонидКилин-н8ж]

Очень приятно слышать как работает инструмент, слышать как происходит процесс изготовления. Спасибо!

[@lz_377]

I feel like this is how machines were created… Somebody just dreamed about someone doing just this and somehow fast forward it X10 in their head.

[@boneheaded9751]

No heat treat? At 58RC you probably lost a couple of hardness points from using the angle grinder, as they create a lot of heat. And depending on how how it got from grinding the bevels as well. Using a jig, and not freeehand, you can't feel how hot it gets. Also probably introduced some stress/uneven grain. I mean looks nice, but not sure about what's going on inside that grain structure, edge retention, and hardness as a result...

[@pjhalchemy]

Bog Oak was a beautiful choice and loved the various tools to make the tang holes and perfect shape. Next a 270mm Yanagiba, and a 165mm Nikiri?? Always a real pleasure to watch your vids. Thanks for all the great work and sharing!!

[@stephaniecureton5657]

I respect any man who uses an angle grinder in flip flops

[@nightfury8848]

I love the black color so much

[@stamatouvable]

Beautiful job

[@AlejandroSanchez-xn4zz]

That's what I call safety footwear! 🤘🏼😀

[@TheScaryName]

Very nice. I would however highly recommend a slimmer cutting disc, I use a 0,75 mm (or 1,0 mm on occasion) and it cuts like nobody's business :)

[@TheWVgoodguy22]

What a simply beautiful kitchen knife, I really like the aesthetic and shape. Great work Koss!

[@TheSilencio86]

It's just AMAZING🎉🎉🎉🎉 I'm cooker .I but one of your knife for testing in real condition in my kitchen!Peace Vincent

[@wayneamelie278]

Such a beautiful blade and handle, mate.

[@Fluffy246]

my mans is really out here in sandals working with metal. respect 🅱️

[@АлексейНефедов-ы8г]

Однозначно шикарная и достойная работа! Приятно смотреть.

[@yeysbaws]

If I have a knife like that, there’s no way I’m using it. I’ll frame it and use it as a display. She’s a beauty

[@mattj.7756]

The time is currently 03:00 Midwest time. I have scrolled so far, this is the last video in my recommendations. I am so tired. I have only been scrolling for an hour, but my body will not fall asleep. I hate nights like these.

Nice craftsmanship!

[@ColdnCruel444]

welp can't say much, you graduated kitchen league, ur a real hubby now, enjoy missy!

[@Bhargav141]

What about the heat treatment and tempering?

[@Timmy2024-y5g]

the steel came heat treated at 58hrc

[@awsomesauce03]

@Naikan Naikan it's hard enough for sure. Just not ideal. If you sharpen regularly hardness isn't much of an issue.

[@aitf99]

You do fantastic work with such rudimentary tools. Id love to see what you could do with good tools ! . Youre a true craftsman.

[@ShannonSouthAfrica]

How are his tools rudimentary? I know nothing about tools, so please revert.

[@aitf99]

@@ShannonSouthAfrica i suggest you look up rudimentary in a dictionary.

[@ShannonSouthAfrica]

@@aitf99 I've got a degree in English, so I know what rudimentary means... What I mean is what is so rudimentary about his tools?

[@aitf99]

@@ShannonSouthAfrica i say rudimentary because he is using fairly primative tools - just look at his home made belt sander. Its very basic. Im not insulting him - hes working with what he has and does a spectacular job. Id just like to see what he could do using good tools.

[@ShannonSouthAfrica]

@@aitf99 Again, I barely know how to operate a standard hammer, so I can't tell the difference between rudimentary and advanced.... lol

[@Wundercc]

I like the use of a the sawzall blade. Think I might use that myself this weekend. Nice knife!

[@marcaycock3759]

Jigsaw blade

[@rickpalechuk4411]

Adding tooth to the tang is a good idea, nicely done. Handsome looking unit. Thanks for sharing your craft Cheers

[@VictorWolansky]

What’s the name of the jig you use when grinding at an angle at the beginning. Wonderful wok.

[@Mex_the_Fox]

Didn't you overheat the steel by cutting it with the angle grinder?

[@kevindorka6328]

i think thats why he left a good chunk of metal to be taken off by the grinder near the cutting edge. the rest was cut directly on the lines. a minimally softer spine wont hurt anyone. the edge itself should be fine with the 3cm he had to take away with a belt

[@alejandrobarberis530]

Sorry if this is a stupid question. What liquid you have inside that container where you put the knife and come out darkened? Thanks

[@belgacem77]

great work...👍👍

excellent job!

[@cristophermorales8420]

Beautiful

[@sran9492]

Just awsome

[@PukaHeadMan]

Nice job!

[@jf8437]

Did i miss the part where he heat treated the steel so as to have some semblance of a rockwell value at the end? Looks nice , but I’m a skeptic on the edge-ability of that steel now.

[@mrskeet270]

J F it was prehardened before he started working the metal. It is a viable option but you have to really be careful not to get your metal hot close to where your cutting edge will be. It’s used a lot in really thin kitchen knives due to their ease of taking a warp during heat treat and quench. It’s not what I do but I know a few that do it this way.

[@xX_Get_Busy_Xx]

mrskeet270 all that grinding completely ruined any temper that steel had before though. Nice looking piece but by no means will it hold an edge after all that

[@tomsdreamshopworx]

Very nice blade! Love the handle design.

[@blaqunikorn]

Love the pluggers mate

[@kabraken]

very cool

[@chrislane1469]

Where did you get that profile, and what liquid is that?

[@RichardOutdoors]

No respirator or pushstick?

[@ciderandthorazine]

like many other knife-nuts in the comments, i've got many questions about this impressive piece. i'm curious about the steel used, whether it was left at 58HRc, and if the knife is in fact zero-ground from a high-sabre?! if it were indeed zero-ground, that would explain the relatively moderate hardness, perhaps - it would ensure that such an extreme edge bevel wouldn't be prone to chipping? all these sorta questions.

[@jamilcastro]

Beautitul work. Do you have the models of knifes? Tanks.

[@f4nt4stic30]

*Great job!*

[@tomaszostrowski5983]

Really nice piece

[@Henkka0Bass]

Awesome crafting, Im waiting your videos and it's a real source of inspiration ! Just a question in minute 05:32 you put the knife in a liquid, wich liquid is it please ? what is the purpose to do that ! THANKS

[@Koss-channel]

it's ferric chloride for blade etching

[@Henkka0Bass]

Awesome work man. I love the way your handle looks like. Classy and good contrast. I wish to ask you for the specs for your belt grinder... In case you build it or if you could give me some tips or general schetch I could use if I would like to build something similar :)

[@olan5668]

No distal tapering at the spine?

[@NJProductions1]

nice, id go with a bit higher hrc for a kitchen knife, especially that size and design the sweet spot for most kitchen knives is 62 hrc. also make sure with a kitchen knife that you grind nice and thi(and i mean thin) the thickest id grind the edge to before sharpening is about 5 thousandths of an inch which is a bit more than the thickness of a hair

[@thequestionmark3394]

What acid did you dip the blade in to get the rough top?

[@MrCYCOFATT]

Absolutely beautiful. Wish i have a knife like that.

[@markolahtinen1635]

That handel! Can u tell speks size on that handle?

[@soumitrasen4880]

Beautiful work of art, but I have an issue concerning the way the handle is fixed with glue. Don't know whether it would last that long as Japanese knives are meant to be.

[@Waffle_cones]

Loved it!

[@toms_martin]

What kind of paper you use..as what I know once grinding on metal will hot and paper will burn..but what I see the paper not burn

Is that a jigsaw blade in vise grips? awesome idea
