This handcrafted tool made in Japan is very useful for multiple purposes. It helps to prepare the leather article for a very precise groove with a line that follows the edge, and by removing the steel edge guide, it can be used as a normal freehand grooving tool.
If you change the grooving blade and replace it with a leather grooving blade, you can use it to make decorations.
The Allen key for changing the blades is supplied with the tool.
