Kaneshin Concave Branch Cutter

Standard shears make a flat cut, but a concave cutter removes a small amount of wood around the branch base, creating a slight depression. This shape encourages the tree's bark to grow over the wound more quickly and cleanly, resulting in a less visible scar.

While it is a professional-grade tool, its intuitive design makes it accessible for beginners. The overlapping blade mechanism provides a smoother, more controlled cut that is easier to manage than standard bypass pruners, helping you avoid damaging the surrounding bark.

Yes, carbon steel is prized for its sharpness and edge retention, but it is prone to rust if left wet. Always wipe the blades clean and apply a light coat of camellia oil or mineral oil after every use to prevent oxidation.

This tool is designed for precision work on smaller branches typical of bonsai maintenance. You should only cut branches that fit comfortably within the jaw opening; forcing the tool on branches that are too thick can damage the blades or ruin the concave cutting action.

The Kaneshin cutter features an ergonomic design specifically balanced to minimize hand fatigue. Its size and weight are optimized for the repetitive, delicate movements required during detailed bonsai styling.
