Leather strap cutter

thingiverse

I use a Leather strip cutter that features a 3mm nut and screw on the rod to securely hold the blade in place. A 6mm nut and screw are used on the handle for added stability, while a 4mm screw keeps the rod tightly connected without the need for an additional nut. The blade tends to become dull rapidly, so it's essential to change it frequently.
