Peters file testing price.
Is $5 per file, a little expensive, but it won't be mystery steel anymore and that's one or forty files. Mark them with a diamond point dremel or whatever you have. Shipping will depend on weight. A simple mark them with a number 1 2 3 4 5... will do. It at least tells you if it's worth messing with. Case hardened 1020-40 isn't going to make a good knife. Grind a shiny spot until there are no teeth.
Mr Garrett, applying Super Blue with a scotch brite pad does the same if you don't want a shiny finish, but probably not as durable as the FC etch. The blue does shine up a bit with 0000 steel wool or light brass brush.
