Straighten warped blades after heat treat and tempering. This method has worked better than anything else I have used. To my knowledge, the technique was shown by Murrey Carter, and I believe he learned it from Japanese master smiths. The Murrey Carter version uses a carbide wedge versus the Daily hammer has a carbide ball.
This will leave up to about a .005" divot.
