I am making a sheering die for my toggle press to knock out simple squares. This particular die will cut 1" and 5/8" squares. I'm using a piece of leaf spring 3" wide and 3/8" thick. I've not had it tested yet, but my guess is that it's plain carbon between 80 and 90 points. I've used springs before for sheering dies similar to this, but I have to say I prefer 5160, which is typically used in the thicker springs--1" and up. Since this is going to be a hot operation, the alloy is not as critical as it would be for cold. As we all know, the difference in hardness is more from heat than any
