Honbay Leather Punch Hollow 4 5Mm Review

I'd say if you plan on using them for leather work or use them a lot, maybe buy something better. I bought them to punch some holes in release paper for engine repairs and such. The language on the packaging was humorous.

Very dull at reception. Didn't work well as a hole punch on laminated paper/thin plastic label stock. Worked best as cork cutters when mounted on a medium speed drill press. Put a few different sizes in a hand drill set to reverse and spin in the opposite direction of the high speed grinding wheel to sharpen the punch sizes I've used the most. Huge improvement.

As mentioned in some other reviews, they arrived blunt. A line was clearly visible along the edge instead of a clean cut edge. After a few uses (I had to cut a few extra holes in some heavy leather straps) the 6mm die (hammer) began to take on an irregular shape. I didn't hit the surface with much force at all. They've worked in a pinch, but as far as their claims that it's heat treated/hardened steel, not much.
