There are some new made wood edge slicker/polisher/burnisher.
We used rosewood, Ebony, Red sandalwood or other cherish wood to make those tools (Send Randomly), sorry we don't have the normal wood version. If you are a skilled leather worker, you will understand the hard wood have very good performance than the normal, soft, light ones, it's construction is more compact, so when you polish the edge, the edge will be more close-grained and more shining.The diameter of the large polisher is about 23mm.
What's more, we developed a kind of zipper polisher, when you make a wallet, the zipper hole is the hardest part to be polished, because the normal edge polisher is too large, if you have a thinner zipper polisher, everything becomes easy now. The diameter of the zipper polisher is 8mm, suitable for the zipper hole or small corners.
