Review on Yaetek Leathercraft Punch Cutter Tools - 7 Sizes V-Shaped Leather Cutting Craft Tool for Straps, Belts, Bags, Wallets (15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm) by Jennifer Roberts

They are loose in the pocket and dull. If you look at the cutting edges, there are large burrs from the "sharpening" process. Get ready to blast a sledgehammer to get them working decently - I had to hit them multiple times to cut through 8 ounces of vegetable tan. I have yet to try to neaten the edges, but I'm not sure if they have any advantage at all. Steel feels very cheap. In any case, they should only be considered as tools for beginners or for people who use them very rarely. If you need them for production use - spend some money on better ones, don't waste money on them.
