I made a new strop for my sharps. 1/2 ×3×12. Walnut. It's double sided, ruff leather,smooth leather. I purchased some Tormek, I have never used this compound before. It is suggested on the package the you oil the leather first to get the compound to penetrate better? I have seen many videos on people using this product on a strop but I've never heard anything about oiling it first. Opinions? Advice? Experience before I apply anything.
