Roundpunch with notch to drill the hole for a collar button . With a blow of the mallet, the hole made will allow you both to keep the button closed and to open it easily thanks to the notch.
It is very practical for closing a bracelet, small leather goods, glasses case, making belt holes or other creations. It can also be used to adjust the size of a strap (for this make several holes to be able to adjust the size).
Straight handle. High tensile steel blade that can be sharpened.
The cookie cutter is equipped with a cutout ejection hole on the side.
We recommend the use of an ERTALON cutting plate to have a clean cut and not damage the cutting edge of the punch.
Steel hammers are not recommended. Prefer a wooden or polymer mallet.

For the collar button to remain properly closed, the diameter of the hole must be almost identical to the diameter of the collar button hanger (the rod) and less than the diameter of the ball (example: 4mm hole for a T4 collar button with handlebar diameter of 3.8mm and ball diameter of 6mm). The thickness and flexibility of the leather must also be taken into account in the choice of the diameter of the hole so that the use is pleasant. A prior drop test is always recommended.
