Usage information:

- This is professional equipment made of high-strength steel. However, punch bits have a limited lifespan. With continued use, they will lose their sharpness. You will therefore have to apply more and more force to make the cut, and they may lose their sharpness and require sharpening. If you use them with a press, we recommend placing a sacrificial piece between the bit and the brass die to extend their lifespan.
- We also recommend tightening the bit securely on your press to avoid damaging the thread. 
- Depending on the leather used (density, thickness...), the leather cut-out may tend to get stuck in the tool's waste channel. To prevent it from becoming severely clogged, we recommend removing the cut-outs after each use with a small metal rod (round-tip needle, round awl...). You can also make cutting easier by applying a little beeswax to the cutting edge of the punch before each use.
