The springs blades I have to make will be about 1/4"
wide and 3" long.
I've re-purposed old hacksaw blades for other uses too. Noticed that
the back of the blade is sometimes different acting material than the
front (toothed side):
"Bimetal blades are made with a high-speed steel cutting edge that is
welded to a spring steel blade back."
Some blades (carbon?) seem to be softer, less springy on the back side.
May just have been the particular blade I was using, but you may want
to keep this in mind if you get unexpected results...
