穿孔鉗

The revolving head lets me switch hole sizes without swapping tools, which is a lifesaver when I'm punching cardboard and fabric in the same sitting. Cuts through leather scraps cleanly too, though I have to press firmly on thicker pieces. Solid little tool for the price.

I bought this mainly for leatherworking and it cuts through 3mm veg tan without much hand strain, which surprised me. The spring action makes repeated holes way less tiring than my old single-size punch.

The revolving head makes switching punch sizes so much quicker than fiddling with separate tools. I've used it on leather scraps and thick cardboard and it cuts clean every time, no jamming.
