Stropping incorrectly can dull a razor very quickly. I think this is the biggest issue new guys have when they get their razors. I had a problem with this for months and I thought all my razors can dull even though they were honed by experienced members. They didn't come dull, I dulled them with stropping wrong. Watch Hi-Bud-gl's (Sham's) video on stropping, it's dead on on how to strop correctly.
