Hey all; I have a 14 point Star case sleeve wrench, made in Switzerland, but it don't want to fit the sleeve very good. Seems like the size that would fit is a bit to small to catch the notches and the next size is a bit too big to go inside the sleeve. So could it possibly be metric maybe? I didn't think so when I bought it because supposedly it came from a watchmakers estate. I did as always clean the case sleeve good so the wrench would have no trouble getting into the notches. Any of you guys have any issue with the star brand sleeve wrench?
