Warped 1095!

[CJS Knives]

just got my blades back from heat treat. the guy i use normally only does O-1 so was unfamiliar with treating 1095.

when i got the blades back they were pretty warped. normally before they are sent out to be treated i straighten them using my arbor press. i place chunks of metal at each end, and press on the center with my arbor press to straighten the blade.

will this process work for a hardened blade? is there a better way to straighten the blade?

thanks guys!

Sounds like a better way than I would do it. I would just use my vise and some light pressure. It could be that your grinding them too thin before HT? But if I remember correctly you've done 1095 before with another HTer and no problems.

i did not grind the edge on these blades at all! they are just cut out blanks.

you might want to use caution when trying to straighten after its heat treated. you already said this guy wasn't familiar with 1095 and he may have them too hard. you try to straighten them , they might break. if they went to him straight, they should come back straight. 1095 isn't that hard to do, I'd call him and see if he will fix the problem.

I dislike linking to other forums, but there is some excellent information here. I have used this method with good (90%) success.

I straightened some 1084 right after I took it out of my tempering oven. Just used some heavy welding gloves and went after it. I was tempering the blades at 400.
