No problemo. If you have sliced a flap out of your strop it can be glued back down with contact cement or rubber cement, Pliobond is good. If you have just small nicks you can sand the strop with sandpapers or use a pumice stone (old school) or use a diamond plate (new school). Make sure there is no abrasive left in/on the leather. A rub with a Scotchbrite pad may help there.
