Joe, if you like to experiment (most of us do here) first try some olive oil or neatsfoot oil. Just a light coating that I work in with my hands. Let it soak in for a day before using. I also like to use a pumice stone on my strops. I just wet the stone and gently rub the leather. New strops always have a break-in period. The more they are used the better the draw.

p.s. The four sided strop from Tony is awesome.
