Overview
A rotary cutter carries a circular blade on a handle and rolls through leather in one smooth forward stroke. It is the fastest way to cut long straight straps, and it excels on thinner chrome-tan and garment leathers where a fixed knife tends to drag.
The trade-off is control. Because the blade is always exposed along the line, a rotary cutter follows any wobble in your hand, so it rewards a firm straight edge and a steady pull. It is less suited to tight curves and to thick veg-tan, where the wheel struggles and the cut can drift off vertical.
Choose a 45 mm wheel for general work and a 28 mm wheel for tight shapes. Buy blades in packs, replace them the moment the cut stops being clean, and always retract the guard before setting the tool down.
Safety
Hazard. The exposed wheel rolls through skin as easily as leather; retract the guard after every cut and keep fingers clear of the blade line.
How to use it well
- Always cut against a steel ruler or straight edge to stop the wheel wandering.
- Use a fresh blade for each new project so the cut stays clean and square.
- Roll the cutter away from your body with a single firm stroke.
- Keep a spare wheel on hand because a dull blade tears rather than slices.
