problem is that they need to be very resistant to taking a bend, so I
need to increase their strength. Additionally, one edge (1" long) will
need to be hardened as it will be a cutting edge.
I could likely harden the blanks using heat treatment, but this is a
PITA at the best of times due to warping issues. Flatness is
important. I will likely heat treat the edge to get a good cutting
I'm considering rolling thicker stock down to achieve increased
strength through work-hardening. This would be done cold, and under
power. I would consider making the rolling mill myself, or purchasing
one if they're available (more time than money these days).
Does anyone have reference material which states the highest possible
strength available through work-hardening of various hardenable
steels, as well as the thickness reduction percentage required to
achieve this state?
I'm thinking of O1, W1 or a four-thousand-series alloy steel.
Additionally, is there reference material available for the forces
required (both torque, and clamping) to reduce thicknesses of
materials at certain hardness? Looking for toolmakers' rules of

Thanks for any thoughts or recommendations. I'll likely poke around in
Machinery's Handbook, but I'm also interested in first-hand
