I had a pair of ice skates form my rearing in Wis., now i live in Az.,...not much ice here nor do i have the inclination.I cut the blades off the skates and made a no. of scraper shapes with them. I noticed they were Sheffield steel.I'm now on a quest for 'found' steel.I've heard that leave springs are made of good steel..is that true? Any sources for salvaged steel that would make a good scraper.The skates are about 5/16", and i would like to find some good steel that is 3/8" or even 1/2".Thanks Rob
