Review on 🧰 Leather Craft Tools - Half-Round Cutter Punch for Crafting Strap Belt, Wallet, and Bag - 7 Sizes (10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm) by Poualss by Hannah Curi

They should only cost $5 and if so 5 stars. I know exactly how they make them. It starts with a metal rod with one end flattened, the flattened edge sharpened, and then stamped again to create a curved edge. The edges are quite sharp. At first glance they don't seem that sharp, but it seems to me that they are. For me, they easily cut through 6-7 ounces of skin. My frustration with how they make them leads to a lack of design. They bend slightly where they broke. I've already had to fix one and expect the others to fail if I use them. Also, as mentioned in other reviews, it's not semi-circular.
