I use cowhide strops and diamond pastes from 28u to 1u. I still have a couple of strops that are pristine. Do you recommend that I keep one without compound for finishing?
The silicates found in natural veg tanned leather tend to be smaller than .05u. Chromium Oxide runs about .5u. Plain leather should be used AFTER using any compounds for the very best edge.
