If you work with clay and do jewelry making, this 3mm calibrated punch is a total game-changer.

No more guessing with straws or toothpicks — this thing makes perfectly crisp, clean holes every time.

The trick is to use it when the clay's fresh with a size slightly smaller than your stone, then go in again with a burr the same size as the stone once it's dry.

You can also make neat stone collars by setting your stone and then punching a hole two sizes up around it.

The edges are super sharp, so you get clean cuts, and it's durable enough to use over and over.

Seriously, if you're tired of uneven holes or makeshift tools, this little punch makes stone setting and clay work way easier and more precise.
