I have a Stinger in SM-100. It is a strange material in that even kept in carefully climate controlled environment, exact same temperature and humidity 365 days a year, the action is wildly unpredictable. Sometimes it is OK, sometimes almost feels grinding. It was permanently "fixed" by the guys at Ferrum Forge, so this is not from anything I am doing.
As a user, it doesn't make sense unless you have some very specific job like demolitions, where you need nonsparking nonmagnetic tools.
The anodizing is not thick like you can get on regular titanium (which is already thin), so don't expect color to stay on a user.
It's interesting, not easy to sharpen on certain stones, perfectly serviceable knife but doesn't offer any advantages except for the novelty of it. If you have the ability to reanodize that might be a plus on a user.
Otherwise definitely has collector value, but doesn't offer any advantages over any decent steel.
