In this video I make a Japanese style of chef's knife called a kiritsuke from 1095/15n20 damascus with an ebony and ironwood handle. Facebook: jacobsenblacksmithing
I use the right handed versions but they are excellent knives with their wickedly sharp edge. Took me a while to get used to the single bevel (and used quite a few elastoplasts to stop the blood flow) but they are the stars of my kitchen.
I've been making survival and bushcraft knives for a few years now and was wanting to maybe delve in to the kitchen knife scene. This vid gave me an isea on what I want to do next. Very well done. Gorgeous end product ! My daughter says it's too pretty to use !! Thanks !!
Im amazed that show still holds its glory to this day. I remember watching it as a young teenager and thinking it was the coolest show ever. That’s when anime was worth watching. What ever happened to those good ideas?
@@michaelsanchez8519 tell me about it... If I see even one more shitty isekai rolling my way Imma flip ma shit! It's not just anime tho.. Manga Comics Games Movies TV ...everything seems to have gone the way of the dodo. Maybe I'm just old and cynical at this point
Small tip for putting the nail varnish on. Cut a small groove in a scrap of wood. Couple of pull strokes with a saw will do it. Put the nail varnish in the groove and then pull the knife through it. Nice even level coat.
Great video, and beautiful work. I'm sure I speak for everyone who has ever studied chemistry, though... ADD ACID TO WATER, not water to acid. Clearly not a problem this time, but just for your own safety, it's a rule for a good reason. :-)
Thanks. Ironically I had taken a chemistry class a couple months before this video, but forgot that rule. It was at the bottom of a big tube so it probably couldn't have splashed that much, but I'll remember that rule in the future :)
it matters when you change the concentration a A LOT and only for strong acids. If you dissolve iron(III) chloride (not really an ACID, it is what you call a Lewis acid) in crystal form the hydrolysis is exothermic reaction. Then you would be right.
Matthew Gore Ive once added water into a 1L beaker of about 300ml 18M sulfuric acid (in a controlled environment of course). it did splash a bit, but it wasn't catastrophic. Anything less serious than that and I wouldn't expect results at all
Your pride in your craftsmanship is second to none. So now I have to ask what you charge for something like that considering the time and work put in to it, thanks
Very nice craftsmanship! Subscribed. A trick to coating the edge easily is to saw a small groove in a scrap of wood, (a hacksaw works well) and brush the groove with nail polish, then run the edge of the knife in the groove.
One quick word of advice. Once you have forged out your Damascus bar, grind off the scale and do a preliminary etch, that way you will be able to see where the welding steel is and be able to grind it out so there's no chance of any of it being on the edge of the blade.
Not sure if it's been mentioned. But a little trick with getting the nail polish on the edge is to cut a groove into a block of wood, fill the groove with the nail polish and run the blade if the knife through it.
cool tip for the nail polish to get a consistent coverage is to pour it on a flat piece of scrap and just run the edge over/through the puddle. a touch more consistent.
A tip, if I may: Turn your body a bit more to the right when you work on the anvil. That way the packet (in your left hand) is more aligned with the face of the anvil. A.k.a. the handle of the packet is parallel to the side of the anvil, the hammer's handle is perpendicular.
Great video and a great knife, you really put in the effort forging that by hand! Thanks for the tip with the curved platen, it's much cheaper than paying out for a giant contact wheel and just as good, I think I'll steal that idea. If I may give you a pointer I was taught to forge damascus round before twisting, then you don't have to worry so much about cold shuts when you flatten the steel out after the twist and it saves the steel that would be lost to grinding. That being said, Keep up the good work!
They sell curved metal platens, but this was cheaper! I usually twist it square then grind off the protruding metal because you get more activity in the pattern the more you grind into it. This helps bring out the "stars" in twist damascus. Thank you!
I had been wondering if there was a better way of hollowing the flat side of a Japanese kitchen knife. It turns out I had the same idea, but was only thinking of it for hand-sanding, not putting it on the platen. 'Tis a very clever, and simple solution for someone without a large radius grinding stone. It's also nice to see others with a Grizzly Belt Grinder!
I have a 1 1/2 horsepower motor on my KMG grinder, and it gets hot after I grind really hard for along time. it might be that your motor isn't big enough for the jobs you're making it do. It's having to draw more amps to keep the rpm's up, and the excess electricity running through it is causing it to heat up.
This is really cool man. I started watching videos on knives and how to make them! I'm still looking and learning. Keep it up man! 😉👌 I also recognized that little piano song! That's from Cowboy Bebop! One of the greatest animes ever!
Mitchel, great video! I really like how you explain your steps. The style of knife is great. I'm just learning, in fact, I haven't yet finished building my forges. I'm in the midst of building a coal forge as well as a propane forge. Then I guess my next big project will be to tackle a 40 ton hydraulic press. I'm looking forward to more of your videos...
Great Video, and cool, someone who makes a Kirituke Knife for a left handed guy. ! I might order one too. It is all about the cost. As I was in Japan i was looking for a knife but they all where up to 60-75% more expensive than for a "normal" right handed knife. That is insane in my eyes.
Fantastic work. I love the handle, ironwood and ebony are some of my absolute favorite woods! The pattern turned out beautiful, as well. I'm actually really impressed that you managed to forge the damascus without a power hammer or striker. I've never tried blacksmithing (but I want to at some point) and I often hear people saying that it's almost impossible to do without the aforementioned methods so I was kinda bummed about that - but this gives me hope that I might be able to do it someday, as well. Subbed!
Like many things, it's possible but just takes more time doing it by hand. If you have someone to strike for you I'd recommend that! Start learning how to forge weld, then try making small billets that you can forge by hand. Thanks for the sub!
awesome knife well done but maybe this is a tip. When you heat-treat a knife dont move it from left to right in the quench it self because that way you have a much bigger change of a worp in your blade just move in from front to back
Beside that amazing piece of iron and wood work, great video production. I am curious what some one might have to pay to get a piece of work like that.
I thought that first ball peine was a mite light, but HOLY COW.. that sledge will put hair on your chest. So far, I like it and I have little doubt that Im going to be more than just mildly impressed with the finished product. Will this knife hold an edge long?
almost all you done well. But remember, japanese people dont use any machine grinding after hardening of steel. Metal becomes hot again ad lose it) So in the end cutting power becomes 20% weak. Before hardening you need to do this stuff. And after only handwork with sandpaper and waterstones. But you made good video, good luck !
@@MitchelJacobsen you wrong. Also after hardening you need to put blade in low temperature about 250 degrees for 1.5-2 hours . It also stabilisation process. Why you think traditional japanese knoves are better in the world?) Because it's a lot of hand wokr even on factory (yoy may search for example tojira knives) even on factory they try to make main part without hit. And if we talk about masters they even forge in not super big temperature, making blade more cold using wet broom on anvil. It's very important steps if we talk about realy traditional way with cutting power wich wiln't go away in 1 year.
That is just an incredible piece of art, honestly best Damascus I’ve seen.
I had to watch this video without audio and understood every single step, im now your new sub
Man, the Cowboy Bebop caught me off guard. Hell yeah, mate.
One of the best knife videos. Tons of hours and patients, and a true work of art.👍
Thank you!
hand forged damascus aint no joke! kudos to you!
That’s not a Chef’s Knife, that’s a work of art
Excellent work, and I'd glad to see you treated it as a tool to slice vegatables rather than swing it around like a weapon - well done sir!
I use the right handed versions but they are excellent knives with their wickedly sharp edge. Took me a while to get used to the single bevel (and used quite a few elastoplasts to stop the blood flow) but they are the stars of my kitchen.

Beautiful knife. Thank you for the detailed explanation throughout.
This is probably one of the closest in terms of craft to a japanese one. I love this!!
Beautiful bit of work! Gorgeous knife.
You do it by hand! It's awesome! I bow before your opportunity to forge by hand such work! Special thanks for the details of the work!
Very cool. I like your style, very charismatic and a well put together video showing great skills!
Small tip for putting the nail varnish on. Cut a small groove in a scrap of wood. Couple of pull strokes with a saw will do it. Put the nail varnish in the groove and then pull the knife through it. Nice even level coat.
That is an absolutely *gorgeous* Kiritsuke!
Great looking knife, and quality video as well
Very good tip for hollowing the back of the blade! Thumbs up.

Do it like you "oughdda" add the acid to the "wadda"
Beautiful knife
My thoughts exactly :)) Especially with sulphuric acid. Though not really a concern in this case, it's usually good to keep to this rule.
Matthew Gore Ive once added water into a 1L beaker of about 300ml 18M sulfuric acid (in a controlled environment of course). it did splash a bit, but it wasn't catastrophic. Anything less serious than that and I wouldn't expect results at all
My cutting skill doesn’t deserve this kind of knife
Someone who knows something more than many popular yt restorators
Awesome seeing how you work!

Who needs the gym when you have a forge ;D
not funny.
@@rastkokomnenic3190 It actually is
To avoid tendinitis you should go to the gym
Yeah, but your gonna have the “magazine” arm for the one that does not hammer.
One quick word of advice. Once you have forged out your Damascus bar, grind off the scale and do a preliminary etch, that way you will be able to see where the welding steel is and be able to grind it out so there's no chance of any of it being on the edge of the blade.
I grind off the welding beads after forge welding to do that!
Not sure if it's been mentioned. But a little trick with getting the nail polish on the edge is to cut a groove into a block of wood, fill the groove with the nail polish and run the blade if the knife through it.

Damn brother that was awesome
Great Video Mitchel I loved the knife your craftmanship and your thinking out of the box it's really inspiring
Thanks friend!
I love ebony, looks more like black plastic than wood in the right lighting.
I loved it. Such a great way to go through all the steps of making the knife. Keep up the great work man😊
Pablo García Canosa Thank you so much!
Thats a great looking knife!! I love your work so much man

It's a b-e-a-u-tiful blade. Congrats. Keep going!!!!
stunning work there squire
That blade is beautiful! Well done!
Love the knife and nice anvil . Looks like a Trenton

I know I have observed it getting quite warm, but I haven't paid it much attention as it wasn't so hot I couldn't touch it.

Subbed
Dude...... Dude.....!! That's a nice knife!!
You ‘can’ rock chop with a kiritsuke, but it’s really a push-pull slicer if you haven’t snapped the tip off already.
What a piece of art! Great knife!
That really turned out beautifully, great job!
Thank you!
Wonderful job

Beautiful knife. Great work !
Absolutely beautiful work
A true craftsmen !! beautiful knife. As a left hander I would love this in my knife block.😀🖒
awesome knife well done but maybe this is a tip. When you heat-treat a knife dont move it from left to right in the quench it self because that way you have a much bigger change of a worp in your blade just move in from front to back

Absolutely amazing piece of art

Honestly if it cuts meat and paper easily its a fine knife so I'm happy
Fabricobbled together. LOL. My new favorite word
that is super fantastic
Pretty cool
Much calmer than alec steel
Beautiful work!
That was awesome! Very nice
absolutly stunning!
Thank you!
You do great work! I wish I can buy quality work easy in my country.
Thank you!
Where are you from?
super cool! thanks!
Legend has it that he records at 15,000fps so we can keep up
thats awesome, id love to have something like that. reminds me of a Viking Seax
Nice work and I like the music too!
What an amazing craftsman you are. It is absolutely beautiful. How long did this take you from start to finish?

I think you should use a ruler or something flat to apply the varnish to the knife edge before the ferric chloride treatment.
Sir good and very hard work, thank you for sharing. Have a
