Thanks for watching. The liquid nitrogen was used to complete the hardening process of the stainless steel for best sharpness. Drop a like and sub if you liked the video 🙌
Stunning blade. I imagine a few different etching options would produce some different contrasts in the metals? But don't change this one, it's so cool to see.
The smashing of the liquid nitrogen banana was a VERY nice artistic addition. I have a question about the steel. What grade was the stainless, and was the other metal a high carbon steel, because I though stainless steel was non-ferrous and wasn't magnetic. Thanks in advance for a reply! 😁😁😁
Thanks for watching! Cryo is used for stainless blade steel to complete the hardening process, it limits unwanted elements from heating improving hardness for a better edge on the blade
Шикарнейший нож, но заточка так себе. При такой геометрии и таком тонком сведении он должен резать в разу лучше. Рекомендую финишировать заточку на коже с полировальной пастой.
The liquid nitrogen had nothing to do with knife-making but everything to do with UA-cam views prove me wrong and I will subscribe to your channel and like you next 20 vids. Nice knife and good clickbait though.
The liquid nitrogen was needed to complete the hardening process of the stainless steel. Without it the blade would be softer. Only the banana is not necessary but It shows how cold the cryo is
It converts any retained austenite into martinsite, completing the hardening. To get the best qualities out of stainless, you need that step. It's a standard practice.
Any well made knife is entirely dependent on a good “heat treatment”. This is a well known basic for knives. Heat treatments in the most basic sense are done by taking a “hot” knife and cooling it down quickly. This shock in temperature changes the grain structure of the steel. Hot is a relative term and the temperature the heat treatment is done is dependent upon steel chemistry and desired result. A room temperature blade being cooled to sub zero temperatures quickly is the same temperature variance “shock” that could be achieved from taking a thousand degree knife and cooling it to room temperature quickly. Ultimately he took the time, and spent the money to get the liquid nitrogen to provide his blade with a very specific treatment to get his perfect desired effect. Knife making is an art of skill and science. Both of which are being mastered in this video.

That would make a World Class Chef very happy!!!
🙌
Gotta love that cryo heat treat!
Also, I LOVE the fuller you put on your chef's knives!
The knife looks beautiful 👏👏
Thanks!
Awesome blade, love it!
Thanks 👍
cool Project! like it a lot!

Thanks for watching. Yes it could be lighter or darker depending on time in the acid
Stunning 👏🏻
Thank you! Cheers!
Beautiful.
Thank you! Cheers!
Good looking knife, great job! Very similar to the one I bought from you...
Thanks, probably quite close to it!

Never mind. I see that the stainless steel only provided the accents in the welded pattern. Cheers!
Yes, the most important step, the Banana.
Without banana knife is nothing 😊
Always remember to cryo quench your bananas 😂
If you could make more banana related content, I would greatly appreciate that!
Will do 😂 was thinking of switching to only banana focused videos from now on
A++++ for the banana 🤣beautiful
😂 thanks 🙏
AEB-L?
Yes AEB-L stainless. Thanks for watching!🙌
master!!!!
🙏
Cool project. Can we apply all process for N690?
Thanks. Can't say for certain, haven't successfully forge welded n690 yet but hopefully soon as damascus.
Can I ask what the cryo treatment does for the blades performance?
Thanks for the amazing video! Love my Griffin knife!

Thanks for your previous purchase also! Great to hear you are enjoying it 🙌
0:31 Is your steel kiln made from soaked lightweight bricks?
Yes it's made from lightweight high temp bricks
coooor, wat a beaut
🙏
Lew, how do you weld layers without flux?
Weld around the seams
What steel is that?
Aeb-l stainless steel core
Why don't u mention grade of iron n steel and formation to get Damascus patron...
HA! FIRST !! :D
😊 gunslinger fast!

Arte.

You guys dip stuff in? Why not explain? Pretend that all your audience don't know what you're doing, not like we're expert knife makers.0:29
It's diesel it burns off to leave a soot for forge welding keeping oxidation away

@@rustjupiter The part about the cryo treatment being the same as taking a "hot" knife down to room temp is false.
@@bigernbladesmith it’s just an analogy
