blade strightening

[neil g]

does anybody know if you can reheat a katana blade after the quench to straighten out some of the curve. if so at what temp, i'm afraid of softening the blade.

Would this be a faster solution for you?

Neil,

If it *doesn't* work, please let me know. I'm not affiliated with the group in any way shape or form... I merely stumbled across that page a month ago and thought it fortuitous that you'd ask about it. I've not tried it.

As I said, if you see any improvement or realistic variation...or if it just plain doesn't work... would you please let me know so I don't recommend it further?

Thanks in advance, and good luck!

I have straightened blades cold and then used them on hard materials like lumber and frozen trees. I think the alloy and heat treatment must have a huge effect. Banite @ RC57 nickel chrome alloys withstand my abuse (I have high impact speeds, easily 160fps plus shown on chronograph).

If your blade is edge hardened it should straighten easily without compromising edge strength, but slip lines will align in the crystal lattice of the soft back via the ductile failure and weaken the blade overall.
