Forged Full Tang Kiritsuke | Knifemaking

Get your Raycon here: buyraycon.com/blackbeardprojects for 15% off your order! Thank you!!!
This Kiritsuke is made of k720 aka O2 Steel differentially hardened and tempered to edge hardness between 60 and 65 Rockwell.
Overall lenght is 280mm with 160mm long blade 51mm at the widest and tapered 3mm thickness.
Handle scales are made of stabilized olive wood, wengè and doussie with cork and black felt liners.
Pins are carbon fiber, brass and brass tubing filled with white resin (that looks black) of 3 and 4mm in diameters.
This is not a traditional kiritsuke, it is my interpretation with western style full tang handle construction and bevels ground on both sides. Still a multipurpose chef's knife like the classic kiritsuke.
Looks like I can't get an hamon line on this k720 steel, this process failed already a couple times for this steel but works very well for other like 1070 (c70). It might have to do with the rather long soak time required (between 15 and 20min at 820°c).
Thankfully the acid etch in ferric chloride revelad a cool steel structure that I quite like and almost looks like a very high count damascus. Still a great steel I think!
It took me a while to decide the handle construction this time, this is why I drilled pin holes on tang later on after the heat treatment. I do not suggest this at all, k720 steel is somewhat hard even if not quenched, drilling took a long time and a broken bit.
I also experimented with punge line, ground it off on near the edge to have the entire lenght sharp but also a flat spot between handle and blade for a straight scale glueup. First time for me, I'm sure it has been done before but I have never seen it myself. I like the effect of the plunge line a lot this way, will do it again!

[@josephmartinez9276]

Hey just a question, have you ever tried an s grind on any of your blade projects? It helps with the surface tension of whatever you are cutting.

[@restorersnotes3225]

As far as I know, you've made a lot of knives if you shave your hair with each one)))) why aren't you bald yet? You don't shave your neighbors, do you?))))

6:45 the drill bit breaks. A sad end for such a loyal tool. The next vid should be in Memorium. RIP. He was a brilliant little drill, always screwing around. He'll be missed by everyone.

[@jacknemo8021]

It was a negligent homicide as he heat treated before drilling....

This is my favorite knifemaking channel.

[@joshua00022]

There are thousands of knife making videos on KZbin, but yours are my favorite. The handle work you do is second to none in my opinion. Great work.

[@allanlabanowski7059]

One thing I appreciate about your content is that you always seem to be striving to improve your craft. It's always excellent to see videos about a new skill you've picked up and then see said skills used practically in projects like this one. Well done video, like always.

[@davids1642]

It’s nice seeing that your actually forging out the “forged” blade.. so many channels have “forged blade” in the description but really they just straighten out and flatten a spring and then trace a blade pattern to cut out with a grinder.. I like Blacksmithing and seeing the techniques used to get the shapes and bevels by hand.. anyone can just cut out a stencil.. and the detail you put into that handle.. damn..

[@lewissammons]

Your knife crafting never ceases to amaze me, you're truly talented! Thanks for sharing!

[@davidchang-yen1256]

Always amazing to see a completely functional item look like an absolute masterpiece work of art. Excellent as usual.

[@grantsteele8612]

Using the vacuum w the stabilizing resin is genius

[@DanielVeja.]

I just have to ask: why does anyone ever dislike videos like this?!

[@sayu181]

i enjoyed the video but left a dislike

[@11jeopardy11]

People probably hit the dislike button on accident, I know I've done it a couple of times

[@evenkeel6131]

Probably epoxy collectors, he used a lot of it in this video.

[@simiamalum5487]

Some people don't like the sponsor spots. Maybe they're upset that a KZbinr is paying the bills. I prefer a sponsor over random ads. At least I know the creator is actually getting paid for it. And... Most of the time they'll throw their own spin on the products as well. This one pointed out that you can wear cordless buds under earmuffs. Nice...

[@sonyhk3824]

Of jealousy and envy they make dislike.,

[@mullerswart3157]

Thank you for sharing your work. You inspired me to start making knives for which I owe you a huge debt of gratitude. 🙏. Take care and stay healthy.

[@Syberz]

You did quite a few videos on the tools you use (mostly because you restored then for use) but ever thought of making a short video on the protective equipment you use? Maybe some examples of what's worth paying more for, what turned out to suck or be a waste of money? For someone like me who's looking at setting up a workspace it would be super helpful.

[@craigljardine]

Glad to see you are back to forging. Awesome project.

Oh boys ! I love the handle 😍😍

I adore your skills. And you update amazing videos! Just a thought to add. In case it it possible, try to make a kitchen knife with a really thin blade. (Thin blade is the real best to cut vegetables.) But if that is not possible, don't worry. Your videos are amazing, all of them.
