Bonsai Concave Cutters

The Bonsai Concave Cutter is the single most important tool for bonsai use and for which there is no substitute. These razor-sharp tools are designed for cutting branches flush to the trunk. The resulting wound can then heal over quickly with little scarring.

The cutting edge is rounded making these act as a concave cutter and a knob cutter in one tool.
These concave cutters have blades that are 2/3″ and have an overall length of 6 1/2″.
