The wheel is used for the decoration of the upper heel edge. In the picture you can see the marks. For refined shoemaking it is a very nice way to give the shoe a perfect finish.
The tool comes with a spare wheel in the same size.
Width of the wheel: about 2 mm
Handle material: beech
Tool overall length: 185 mm
My tools are all used quality shoemaker tools in ready to use condition.
