Sterile Knives???

[beanbag]

Maybe the answer to this question is obvious to everyone else, but I've seen people list their knives as "sterile" on some sales threads.

Pardon my ignorance, but the question is, WTF is a "sterile" knife?

one with no marks whatsoever on the knife. no maker's/manufacturer's mark, no model name/number, no steel type, nuttin.
