You need to clear out your PM box. I can't reply to your question. Anyway,Enco and Victor Machinery Exchange in Brooklyn,N.Y. both sell tool steels at reasonable prices. Especially check Enco. 1/8" will be fine. You will get Sheffield steel cheaper than Starrett,but modern steels are carefully formulated,and Sheffield will be fine. Some insist on paying more for Starrett,but the chemistry is the same.
