I didn't like the rough canvas I had on the back of one of my strops and didn't get very good results from it. So I had a pair of denim carpenters jeans that were tore up so I decided to make a denim strop. I just did 100 laps on the denim then went to my latigo then to my horse hide, and the denim really helped smooth out the edge quite a bit.

Now what is your stropping progression, and what types of odd materials have you had success with?
