Not really.Maybe leave it out in the weather,but I wouldn't do that.It could be stainless,I just don't know.I don't talk to the guy that makes them.The handle looks like micarta.He builds the knives tough like a tank.Sorry I wasn't much help.
Put a few drops of vinegar on it and let it set for a day. If it's S/S noithing will happen. If it's Carbon, the spots will turn black. Don't worry you can steel wool them off and if it's carbon it won't matter anyway? I can pretty much bet from looking that it's S/S., I'd recommend doing the vinegar on the top of the spine close to the handle just in case if the thought of it bothers you?
