Rather than start a new thread I found this one from last year. The OP asks the same question I have.
I recently bought two Ontario Gen II SP50 knives with Kraton handles. I didn't know these had been discontinued (unfortunately) and consider myself lucky to have found them.
One handle is shiny black but the other one is covered with a white, almost powdery substance, as described by the OP, which makes the handle look gray and dull rather than black. The OP says he cleaned his handles but didn't say how. I tried wiping it off with water but that didn't work. It's obviously somewhat imbedded into the Kraton. Before I try anything else I might be sorry for I wanted to ask if anyone knows what it is and how to remove it without damaging the handle?
Thank you....
