28 cut out, heat treated, cryo’d, and tempered yesterday and today with another dozen cut out to do the same to tomorrow. This was the last few from today.
All testing at 62-62.5 in aeb-l with only two with very slight warps that needed a few hammer taps.

The Procuts from yesterday tested at 65 and the 52100’s were 64.
Having the ht oven and dewar has been a game changer (seemed like I just bought them but looking back at my equipment notes while waiting for the oven to come up to temp they are a little over 3 years old, time flying by!).

Great when plans come.together.......!!!!! The days may seem.long but the years.fly by...😉......
 
I've got a small batch going in AEB-L.
One did not survive the straightening attempt..
Things were progressing nicely until the shop caught fire.. kind of side tracked me..
Anyway here they are.

How'd you straighten it? A carbide tipped straightening hammer should straighten just about any warp in a blade without cracking it...
 
Oh no.. I did it the old fashion way.. a big vise with 3 point jaws...
And cranked it till it popped..
AEB-l is some pretty strong stuff.
It was after the 1st temper cycle. It RC tested at 62. The grain was very smooth. At least the heat treat seemed to work out.
Do the carbide tipped hammers work at that RC level??

That's how everyone would've done it I think until we heard about the carbide hammers. They actually do work extremely well and they've fixed dozens of blades for me. They definitely work with AEB-L at that hardness because I primarily work with that steel at that hardness and can testify along with many others here on the forum.
I got mine here on the forum from jll346 jll346 and would absolutely recommend them to anyone wanting to stop cracking their nice blades- it really works!

Thread 'Carbide Blade straightening hammers'

THESE ARE USED TO REMOVE A WARP FROM A HEAT TREATED KNIFE BLADE. SEVERAL VIDEOS ON YOUTUBE.....SELL FOR $150!!!!!

I was in need of a carbide straightening hammer so I made a few. NOT EASY I WILL SAY!! They are drilled and PRESS FIT with a 6 ton press. I did add an adhesive but definitely not necessary.
These are 8oz ball peen hammers with a 3/8" SOLID CARBIDE ball bearing. Handles are finished in AXE WAX! These are the highest quality ball bearings available.

Size: 3/8" (0.375" inch)
Grade: G25
Hardness: 90 Rockwell
Sphericity: 0.000025
90Rc.

PRICE IS $90 each SHIPPED. PM IF INTERESTED
 
I might make one to see how they work.
The balls aren't very expensive and I have a bunch of ball peen hammers laying around..

They work great. The only time I’ve had trouble with one was straightening out a knife with a hamon. I had to go back to the three point method for it. Aside from that you can pretty much watch one straighten out as you tap it. I’ve got both ball peen and cross peen style carbide hammers.
 
it'll be awhile before I get to it, but I'm starting to envision this new thing:
