I always strop 40 times on the linen side, and 75-100 on the leather. I strop 25 times on the leather when I'm done and have thoroughly cleaned the blade and dried it. Then I put a few drops of oil on the blade and return it to it's case.

I don't know if this is correct or not, but it's sort of a superstition thing with me. It seems every time I strop less than 75 times on the leather, something bad happens that day. I've been doing it since my Marine Corps days in the late 60s. If nothing else, I always get a baby-butt smooth shave and seldom cut myself.

Semper Fi!
