Matus- i'm talking about the $33-52 models, made with white steel, not the higher end types. Surfergringo just had an interesting post where he ground down one of the folding sheepsfoot salt blades to a wharnie profile, and then filed some of the teeth off a full spdyedge. he just did the tip but no reason you couldn't do most of a blade, if you wanted.

p.s. IIRC, it was the pacific salt-black handle
