I in this episode I will restore a Japanese kitchen knife with a lot of rust. Rust has eaten a lot of the steel away. Also the handle was not in good shape and the wood had split. I started by removing the handle. I used block of wood to hammer it off the knife.
I removed most of the rust with a laser rus remover that was loaned to me by W2M laser: w2m.fi/en/ Next I made jig to help me grind the bevel of the knife to my wanted angle. I needed to remove metal that was left porous by the rust to get a nice even edge. Otherwise the end result would be like a very unven sawtooth knife. After grinding the blade I sanded it all the way to 2000 grits and polished it.
For the new handle I used a piece of aluminum pipe which I bent into an oval shape and made a plug from birch to fill it. I cut the rough shape of the tang of the knife in it, but I left the hole a bit too tight on purpose. I did the final fitting by heating the tang with blowtorch and burning the hole to the correct size and shape. Next I took a piece of Finnish curly birch and drilled a hole for the tang. I glued the handle pieces together and sanded the wood down to teh shape of the aluminum pipe. The aluminum was then polished. The blade fit the handle firmly so I didn't add any glue. Finally I sharpened the knife with a sharpening stone.

Great line, isn’t it?
But normally u never hear this line on *THAT* route...🔪
@@shinypichu1819 Oh god. I don’t wanna hear sans asking if his dust brother wants anything from grillbys
@@tsuhosh don't worry u don't hear that... It will always be the crack of your soul first 😜💔
My hopes and dreams died a long time ago… RIP
The rust removal is always so satisfying. It's like a visual backscratch.
I was literally thinking the same thing before I saw your comment. It really is. 😄
It never gets old.
There's nothing like etching a scratch...
@@marklammas2465 Nice one. :)

Whoever forged that blade originally must be so pleased to see it restored and treated so well. This was lovely.
Hello!
I'm from Russia. In my opinion, people who repair things are great! The current era encourages all of us to throw out spoiled things and buy new ones. But! I am of the opinion that restoring old and broken things is more correct! Good luck, master! I wish you good health and good deeds! You are just a hero of the current era!
That's such a beautiful type of wood, I've never seen it before. Goes really well with the restored blade, nice work!
Birch. Called "Masurbjörk" in Swedish.. Curly birch
@@42Hertzer Sheesh, I misread that as "bitch" and was confused for a second.
@@olivercharles2930 lol!
Thanks for sharing, I was curious! @@42Hertzer
I don't know why but this video just makes me relax seeing someone take care of rusty items.
Asmr odd tinkering 😂😂😂😂
With you on this 💯%
Welcome to restoration videos, your new addiction
After a long experience with knives I only have the one tiniest complaint. The grip not being more aggressively indexed to help maintain the direction of the blade during use. Other than that this is amazing.
This is a traditional handle style for Japanese knives, another traditional style is hexagonal for better indexing.
@@Masononi Love learning new things. That's pretty fantastic. Though I am sure I would prefer the hexagonal one in my actual hand for use.
@@TheWeaponshold I do much prefer them, also I made a typo they're octagonal not hexagonal. They just feel a lot more confident, especially with wet hands.
The very edge of the blade could have been reorifiled a bit more as it a bit too bellied for my taste
"Looks like it was held together by hope and dreams" best line ever.
1:25 i asked myself "is there any steel left under so much rust ?" Great job buddy ! Congrats 👍
really rusty indeed.
iirc rust is 2x iron, so that rust came from half the amount of iron. Plus the rust is flaky and loose, not tightly bound like iron, so one estimate I saw said 10:1 ratio, so if you 10 amounts of rust, it came from 1 amount of iron.
Beautiful wood! And I love texture contrast between the shiny edge and the pitted body of the blade. A really great restoration.
Yeah, as if to say, “The lost and forgotten can always be redeemed. This knife is proof of that!”
8:30 "I think it's now ready" very much made me laugh
Duck oversees progress and finish. The duck is the quality control officer. Probably the best restoration channel on CZcams in my opinion. Great content. Thank you! From Scotland.
Cleaning off the rust with the laser is so satisfying! Also, I love seeing how you make things (i.e. the jig) to fix other things. I think most restorers end up doing that, but it's always fun to see how other people worth problem solve!
What an elegant item! I like how there is texture on the blade from where it was rusted before, really reminds of its past life as it goes forward into its new life
You
Yeah, I would have sanded it😂😂
His videos are dangerous. Idk how many times i've hurt my face after dropping my phone on it when i fell asleep watching his videos..
That rust remover was like watching magic....
Was it? :O
THAT IS MAGICAL. *-_-'*
The close up with the laser rust removal was literally the most satisfying thing ever. And great job. I love your work and the ability to turn knives back into its original glory is an art. Good job. And thank you.
And BTW I don't mean glory as in brand new I mean glory as in the original purpose and meaning of that glorious blade.
Its always so relaxing to watch your videos. Every day is hectic and your videos have just a comforting calmness. Awesome restoration as always btw.
This was worth the wait. The fact that you are still showcasing some amazing and unique ways to fix things always puts a smile on my face
What’s up, dude! Fancy seeing you here!
The laser rust removal is cool and all, but am I the only one who finds it so much more satisfying to watch the rust disappear with sandblasting?
I could never get my fingers as close to dangerous saws and stuff as this guy does, sheesh
I can count all my near misses on three fingers. All I have left. Kidding but had a couple wake me right up and use more safety rigs.
Same goes for using a sander to.
@@crimsongamer2337 One of my exciting ones was wire wheeling a small chain on a half HP motor setup. Caught it and whacked the crap out of my hand, almost broke fingers. Ow. Estupido
“Ah the sand blaster part, I love this”
*laser blaster*
Mother of god.
The handle is a perfect complement to the way the blade looks! Well done!
Dude the laser cleaner was insanely satisfying!
I loved the end where the sharp knife cuts straight through paper! Visual therapy 💯
“It looks like it was being held together by hopes and dreams.”
It was probably using mine then.
ちゃんと砥石を使っているのと、片刃で研いでいるので素晴らしい。
古くなった物がまた使えるようになっていくのが、観ていてとっても心地よいです。
次はどんな物を直すのか楽しみ！
Very beautiful work from you and the Ducktor!!!
👍🏻👍🏻👍🏻❤️❤️❤️
Why would you make the handle in two pieces?? Surely that give it an inherent weakness.
Dunno i guess its to stop splintering or something maybe?
I didn't think you could remove the handle like that, it's great
metal heavy wood light

The laser is my favourite! It’s just so satisfying and I’m addicted.
Always a relaxing pleasure to watch.
If anyone knows, I have a couple of question :
1) Why are the wood of the handle and the one stuck inside the metal part not just one block ?
2) Is there any danger that the heat applied to the part of the metal of blade that goes into the wood could mess up the heat treatment of the blade ? (thinking of it ... considering the rough shape the knife was at the start, heat might not be the worst thing it had to endure :p)
Thank you to anyone who would care to enlight me.
Cheers !
@@StickyGelatin makes sense.
Thank you !
@@StickyGelatin Is it stable enough to apply downward force if the handle is in two parts like that?
1. Ease of fitup. The front portion (bolster) is friction fit to the shoulders, or in this case, the forward portion of the tang. This keeps food from getting down in to the handle since it is sealed around the tang from the friction fit. The lower portion of the handle can be drilled out much larger so the tang can easily fit farther down in it. As long as the bolster seals with the rest of the handle with either epoxy or just a pressed seal between the two pieces, food can't get in there either. So the two part method is to make a friction fit at the front while still being able to drill deep enough to fit the whole tang in to the handle
2. Yes, it COULD mess up the blade, but being as only the tang area was heated, it's very unlikely that the heat bled far enough in to the blade to mess with the edge hardness.
-Spicy Mike
It certainly won't be as strong with the 2-part handle design. But if it's mainly for show rather than actually being used as a knife then I guess it's ok.
@@SpicyMike319 Oh , I see !
Thank you for those info !
Thanks for the video, always enjoy watching!
Only criticism: not using rubber jaws or a cloth on your vise when clamping the aluminum ring. Causes unnecessary marks/work
It all got cleaned off in grinding and sanding.
A Lazer cleaner will be on everyone's wish list! So satisfying to remove rust so fast 👍
'Held together by hopes and dreams' ... Knocked cold by the hammer of time 😅. Awesome work Odd
I actually prefer watching him use electrolysis to remove rust, I find it more interesting
Leaving the corroded surface was a stroke of genius. The texture is amazing.
Well done and keep up the good work!
🙂👍🇬🇧
Unfortunately it will negatively impact the performance of the knife. It was the one thing that needed to be done that was missed.
@@nocjef Very true, although I expect that it'll probably be used for light kitchen use only.
these videos are always so mesmerizing and soothing. very satisfactory to see these items come to new life. top notch work. amazing
"looks like it was held together by hopes and dreams" has he struggled to take it apart.
Ducktor! Always brings a smile to my face.
This knife is beautiful! Great restoration. It wouldn't be so beautiful if it weren't for your talents. Thanks for sharing.
Very interesting comment
Wow, your workshop looks nice!
That knife is surely more of a display item rather than something you'd use in the kitchen, but I really like the contrast of the polished edge and the rust-pitted rest.
I think it looks so cool with the pitted part left as is!
Nice 'Deba-Bouchou' (Deba-knife,pointed carver).
This Japanese kitchen knife for processing fish.
What a wonderful piece of art!
Would like to see you restore a really old website, using squarespace. Think that there might be some good options out there. And the laser clean part, might be replaced with CSS cleanup.
There might be a joke in there somewhere. Anyhow, i love your videos! Keep it up!
Haha you actually got me! "I think it's ready". I was thinking this doesn't look quite like the quality renovations you normally do.
what differs you from the rest of youtube restorations is that you are making jokes and its great as I also always attend everything with humor! it makes your videos way more inviting and involving than others! thank you very much for your content!
Seeing your fingers so close to that saw and the drill had me like 😳😳
Gluing the bolster onto a separate piece instead of just fitting it to the piece of birch was kind of a bruh moment...
And then just tapping the handle into place and not using any epoxy or anything on the tang. That handle won't handle actual regular use for long lol.
Won't matter anyway because it will never hold an edge with the ruined temper.
This was kinda weird for me as well, actually feels like more work for a worse result.
I was wondering the same thing. I’d love to learn what the reasoning behind this was.
@@pieter-matthijsbolt6375 why would the temper have been lost? I wouldn't think simply sanding it would have heated it up enough to do that?
Dude I love the finish on it!
Love it!
That laser cleaner is almost like cheating😂
It's amazing there was any viable steel left under those Ferrous Cornflakes... :S
Amazing... that laser cleaning machine is awesome !!!
The birchwood is just amazing and I loved the laser rust remover. I believe the knife to be a Deba, mainly used for cutting down whole fish, filleting, head removal etc. They're thick bladed and useful in breaking down chickens and other small boned meats. They're bloody handy and prized - I have to whine and beg my brother to return mine after his fishing trips.
This is really informative and useful. Thank you for this amazing video.
My friend at this time; There is an earthquake in my country in which we lost thousands of people. Moreover, I live abroad. No, I did not know anyone; but every dying life consumed me a little more. I came across this fascinating video to take a breather. I love remodeling videos. It's like therapy to me. A three-stage therapy: 1. Watching2 Therapy with the dream of practice 3. Nirvana, that is, therapy while applying. Great workmanship, amazing result. Perfect shots, angles, lights, subtitles. Creative art. If a youtube short documentary special award is given one day, or Oskar (I'm not kidding / note) he is my candidate.👌
You will never be Jun's Kitchen
Awesome! Thanks for the video!
Who else thought this was Kawame Japan the knife guy for a second? Had to double check that it was Odd Tinkering.
Amazing job man! I love seeing how it is possible to turn garbage into gold.
Salute from Rio de Janeiro - Brazil
I'd be worried about steel hardness after the initial grind (heat from friction could ruin the original temper) - definitely check and heat treat if needed.
The original heat treatment is ruined. From grinding without cooling and then also the blowtorch on the tang... frustrating video.
@@pieter-matthijsbolt6375 boo hoo poor thing
Beautiful work!
Always an amazing job!
I only have 2 complaints, why didn't you grind down the other side of the knife, and why didn't you use some epoxy to keep in the handle?
The style of the knife has a single bevel, and to make it easier to remove in the future
I work with Japanese knives, this one is a fish butchery knife called a deba. They are traditionally single bevelled, so only need to be ground on one side 🐟 🍣
It looks great and love the handle!!
Enjoyed your video and I gave it a Thumbs Up
Any other Forged fans initially groan seeing him do the burn-through on the guard then catch themselves, realizing that he can, in fact, take his time to do it? Or was that just me?
Another awesome video from my favorite restoration channel!
Yeah, same with the slow application of epoxy haha. All those high risk methods in Forged are fine when you have infinite time to do it right
I will say it every time - the laser rust removal is SO great. I KNEW it even before... I was like HERE COMES THE LASER! Also, DAMN didn't expect it to be so sharp with the paper slicing! Didn't think after all that rust there would be any structural integrity in that steel anymore. Nice job as always. The Finnish wood is also beautiful.
Wow...that sure is a fancy-schmancy laser cleaning machine...it's even better than a sandblaster! My new favourite tool...
Watching the rust come off with the laser, it’s like wow, how does this happen!? Your videos are great thanks haha!
A really nice job. Carry on!
This is S✨A✨T✨I✨S ✨F✨Y✨I✨N✨G
I love ur channel for one big reason, the Ducktor !
Another great restoration! These are incredibly satisfying to watch. Thank you.
Another stellar video 👍
Beautiful!
Pirate metal band Alestorm approves of the ducky.
Thank you for your hard work!
At this point, you are really multitasking. From consoles to tools, you are just Amazing!
was there any way to get the rest of the blade to look smooth?
You gotta wonder how many meals this knife has prepared.
Remember you used to make knives?
Nice work!
You are incredible, congrats
Odd: "What have you got there?"
Ducktor: "Quack! (A knife!)"
Odd: "No!"
so are you going to harden it and temper it in part 2?
Im between amazed and horrified by that laser
Comment from Japan.
This type of Japanese kitchen knife is a fish slicer. The most important point is variable blade angle.
The tip of the blade is sharp and thin, and proximal blade is thick in order to chop the fish spine. If you can, please check Japanese real knives and remake it.
And 5000 grid is too fine for the first glind for the knife. The reverse side of the stone, 2000 grid, is suitable.
Good job, bro!!!
The laser on the rust was oh so good.
That Lazer is some James Bond shit, it looks so cool!
I feel like the blade itself could get a bit more care but the handle is simply out of this world :) amazing :)
Cleaning rust with laser is so much better than boring sanding.
I got an ad for a Japanese knife watching this video.
Just imagine that kiwami Japan does this handmade... He is in incredible, but you too 👏
I like the "held together with hopes and dream" 😎🤠🤓.
yikes that handle isnt gonna last. it should have been wood all the way through with a metal band wrapped around it. the glue should have gone on the tang of the blade then inserted into the handle. it may hold now but i feel like its gonna come apart eventually.
My thoughts exactly.
