Wifehelper Knob Cutter Bonsai Cutter

The concave design is intentional for bonsai work. It allows the cutter to remove a branch flush with the trunk and create a small, spherical depression, which helps the tree's bark heal over the wound more cleanly and with less visible scarring.

This knob cutter has a cutting capacity of 25 mm. While it is robust, you should avoid forcing it on branches thicker than this to prevent damaging the blades or the pivot mechanism.

Yes, the design is ambidextrous. The ergonomic handle shape allows for a comfortable, secure grip regardless of which hand you prefer to use.

While stainless steel is naturally resistant to rust, you should still wipe the blades clean after every use to remove sap and debris. For long-term care, applying a light coat of camellia oil or a similar tool lubricant will keep the pivot moving smoothly and the blades in top condition.

This tool is specialized for bonsai maintenance, specifically for removing knobs and protrusions. While it can cut small branches, it is not designed for general garden pruning and may not be as efficient as standard bypass shears for those tasks.
