When the leather overlaps or is sewn back,
for a good and clean finish, add some effort to the thick leather for each part.

The machine used is a leather-making machine with a knife.
The excess leather is removed by passing the leather through the set thickness.
It can be partially stepped or diagonally squeezed like a slope.

The blade will soon lose its sharpness, and if you force it through, the leather will stretch.
Maintenance is indispensable. Each accurate work will lead to one beautiful leather accessory.
