Making an Outdoor Chef Knife

What animal would you name this knife after??

[@stardusk1726]

a bore

Pretty good video, your editing and fit and finish are very nice. As the heat treatment of AEB-L is Definitely not beginner friendly. I'm glad you stated it was a good beginner "stainless steel". Have you done any hardness testing or edge retention testing on your blade? I have a feeling you didn't hit your intended as-quenched hardness throwing off your after temper RC value. Heat treating outdoors drastically changes the visual color of the heated steel making it difficult to ensure you were at 1975°. Forges are very difficult to HT stainless in as keeping the temp constant throughout the soaking process is almost impossible without a needle valve gas adjuster and a pyrometer. An austenitizing temperature of 1975° is used if you are also doing a cryogenic treatment with liquid nitrogen. With your austenitizing temperature so high, and no cryo treatment your blade would probably quench around 60RC. I couldn't find any tempering data with an as-quenched hardness that low but I would estimate that you will reduce your RC value by 3 to 4 points with a 350° tempering cycle. The other issue that could be a concern is your austenitizing temperature and soak time. Without a long enough soak time at that temperature you could easily have a large amount of retained austenite within the steel. If I had to venture an educated guess I would say your blade is 56-57 RC. Anyway, that's my 2 cents.

[@99echo]

That's some useful 2 cents there my friend and right about where I think I am as well. I did take readings with my pyrometer that had me right around 1975F which only needed a 5 min soak compared to a 30 min soak at 1950F. Without cryo though, like you said I miss out on a few HRC points. Happy with the edge it took and it's currently being tested in the kitchen by a friend to see how it holds up. I appreciate your insights! It is quite literally my first SS chef knife and all the tips I've been getting should help make the next one even better. Happy holidays!

Absolutely gorgeous! I love that you went with AEB-L. I just watched a video of a beautiful knife but 440C was used and I just shook my head.

[@99echo]

Thank you! Really proud of this one. I did hear that 440C has some crazy heat treatment requirements.

[@miscellaneous5268]

Crazy skills, love it!

[@99echo]

Thank you!

[@vrod1a]

Excellent craftsmanship 👍

Much obliged, thank you!

[@pscottbx]

Very nice job.. what was your starting dimensions of your AEB-L if you don't mind? Looking forward to the next one

[@99echo]

Thanks Scott! The bar started off at 2"x13" with a 0.1" thickness. Glad you enjoyed!

[@lamproknives]

Awesome video and great knife !

[@kims2r]

This is amazing😍 awesome job, that handle is so beautiful👌🏻 how many hours does it usually take for a piece of art like this?

[@99echo]

Kinda words my friend, thank you! Honestly a lot longer since I'm filming it but I'd say a good 12 hours of active work.

[@vdsgma]

You and your channel have bright future.👍🙏

[@99echo]

Really means a lot, thank you 🤜🤛

[@courtneesdad]

Beautiful knife 👍

Thank you!

[@emeraldplatypus9870]

found you recently and love your vids, but AEB-l being a good steel because of easy heat treatment?? You might wanna look again at the austenising temp, the preheat cycle and the fact it need to be cryogenically frozen... EDIT: in fairness, its an easy steel to get to an okay hardness, but if you really wanna push it, then its as hard as something like m390

[@99echo]

Hey thanks for watching. I did say good "beginner" stainless steel and I do follow the manufacturer's reccomended temps for preheating, austenitizing and tempering. Cryo is definitely ideal for max hardness but I wouldn't call it necessary. I like to use steels that beginners can easily work with and AEB-L is the only stainless steel I found that you can harden to a useable HRC without an oven, steel foil, aluminum plates, air compressor, LN2, etc. Agreed?

[@kinardoutdoortv873]

Nice

[@cortneynelson2213]

Great job bro. U need to go buy that harbor fright porta band. !!!!!! U wont regret it i promise

[@99echo]

I know! One of many things I need to upgrade. Did you get the swag table for it too?

[@cortneynelson2213]

@@99echo not yet gotta sell a few more knifes to afford it right now i just got a cheap wood vise from harbor fright and mounted it in there. Also i bougnt a foot pedel switch also from harbor fright. It works great

[@99echo]

That's my thinking, trying to upgrade over time after making some sales. Foot pedal sounds awesome! I'll have to check it out

[@andrzej1242]

Piękny !

[@richardloukota6973]

3:43 I would like to know which wood you used🙂

It's dyed and stabilized box elder burl!

Nice job 👍 it looks awesome! Is there a link to the sketch?

[@99echo]

Thank you! What do you mean by sketch though?

@@99echo your drawing of the knife

[@99echo]

I slapped it on the steel as a template 😂 you can see it there in the beginning

[@Timmwe]

@@99echo I meant if you have a picture of it for download so we could remake this 😅

[@99echo]

@@Timmwe LOL no but my instagram has some pics you could probably trace 😂. I'll think about that for future vids for sure

obrigado!

[@Michael-w8v]

0:06 Is this knife not cut a piece of paper easily without folded?

[@99echo]

Freestanding? Haha no I don't think so. Might need to make a light saber for that.

[@ahmadali2254]

AEBL is stainless steel never quench in oil

[@andrewfischer6055]

you can oil or plate quench this steel.

[@ahmadali2254]

Yes but plate quench is more clean and best results

[@andrewfischer6055]

@@ahmadali2254 absolutely! cryo is good to for the remaining ites.

[@99echo]

Yeah if I continue to work with this steel I'll definitely plate quench and wrap with SS foil. Save me some time and make it as hard as possible

[@ed.sol.crafts]

I would to know he was able to measure the temperature to make sure he hardened the blade. My bet is he didnt.

[@abbythao6]

How much do you sell you knives? Interested. Lmk

[@99echo]

Hi, I think I already responded to this on another comment. You can reach out via DM on instagram if interested @99echo. I don't give prices here

Quel acier pour la fabrication de ce couteau ?

[@99echo]

AEB-L stainless steel

[@chinthakawimalasooriya5629]

Pls let me know the type of glue that you used

[@99echo]

It's just a simple 5 min epoxy

[@sedatozyol6765]

Nice knife making heat treatment ??????

[@99echo]

Thanks! 1975 F for 5 mins then quenched in oil. Tempered at about 375 for 2 two-hour cycles. It's not the best heat treatment for AEB-L but it worked!
