Know before you buy
Concave cutters are specifically designed to remove branches flush with the trunk. By creating a slightly concave wound, the tree's callus tissue can heal over the cut more evenly, significantly reducing unsightly scarring.
Yes. The tool features an ambidextrous design, ensuring that both left and right-handed users can achieve the same level of precision and comfort during pruning.
No, these cutters do not use a spring mechanism. The manual, bypass cutting action is designed for deliberate, controlled cuts, which is preferred by many bonsai artists for delicate shaping work.
While the stainless steel and rust-resistant coating offer excellent durability, you should wipe the blades clean of sap and debris after every use. Periodically applying a light coat of camellia oil will help keep the pivot point smooth and the blades protected.
While the 8-inch length provides good leverage, you should avoid forcing the tool through branches that exceed one-third of the blade's opening capacity. Forcing cuts on overly thick wood can damage the precision alignment of the bypass blades.
