I found a Scrapyard knife forsale online that I'm looking for information on. The seller says its a Street Scrapper 5, but I don't see that model listed on the Scrapyard website. Can anyone tell me if such a thing exists and if so what steel its made from. I've been wanting a SS4 for my fist piece of INFI but if these are made from it as well I'm going to jump on it. If its not INFI I think I'll pass.
