Straightening high speed steels.

[Scaniaman]

I guess I will just have to try it at that price point. I thougth it's more about making small indents then putting a lot of power behind them.

Try it, but it was very light. The hammer I built on is 460 gram. Feels about right.
Here are som pro stone carving stuff. Hammer a little on the heavy side I suspect. I have one if the Bavaria chisels.

My issue is: when you grind the divots out, won't the blade warp again?

S Storm W , how thin was the stock? and how thin did you grind before heat treat? I have some 0.062" M2, after reading this i am thinking profile only before HT.

No it doesn’t at all

Interesting... I'll have to try that. Beadblasting hasn't worked for me in the past, as soon as I grind the blast off it bows again

There were a couple of thicknesses in the 0.100 range.

I don't know if this will help, but I recently watched this video of Murray Carter straightening some blades, and it was new information to me.

This isn’t high speed steel but 52100. But gives you an idea of what the carbide chisel marks look like. They are less pronounced in high alloy steels
