Review on Bleiou 7 Pieces Leather Craft Tools: Arc-Shaped Half-Round Punch Cutter Set for DIY Crafting of Straps, Belts, Bags, Wallets - 7 Sizes (10-40mm) with Polished Finish by Summer Hendricks

You get what you pay for. I was hoping that the main issue would be sharpening, which I could fix. 1) The edges of some of them had dents that needed to be removed. 2) The major bevel is on the outside of the curve (good), but there is a very small minor bevel on the inside. As with the chisel, I expected a one-sided bevel with the flat side to the skin for a clean cut. So to repair you need to grind to remove the inner bevel and then add the outer bevel. 3) It looks like the outer bevel was done in a hurry without making sure the edge didn't overheat. Magenta discoloration of large parts. 4) Very rough matt surface of the parts. You could make a career out of trying to achieve a nice glossy finish.
