The bonsai Nibblers came about because I wanted to see if it was possible to make a small diameter carving tool that had replaceable cutting tips. Most small (under 16mm) rotary carving tools are a one piece construction, which has its advantages but also its disadvantages. If you chip or damage one of the cutting edges on a solid tool you have to throw away the whole tool. If you blunt, chip or damage a Nibbler cutting edge you simply turn it to a new edge.
The Nibblers have been designed and are manufactured by myself in a modern, state-of-the-art CNC manufacturing workshop.
I have been working in Mechanical Engineering and Product Design since 1992 and have been active in bonsai since 1998.
