I have a few different strops, paddle strops and a belt or two.
The strops tthat I use the most are 2 1/2 inch wide models. The finest one is called a Mahogany and is super slick.

Today I got lucky and purchased two very large pieces of leather for $4.75 at an estate sale. I will be making some paddle strops and a regular strop from this material for my own use. Its about a 7 oz weight so not exactly as thick as I would like it for a traditional strop but for paddle strop's it will be just fine.

More toys!
