Kaneshin Knob Cutters, 150mm

The knuckle cutter, also known as a spherical knob cutter, is an indispensable tool for precise bonsai pruning. After removing a branch, it's crucial to eliminate the remaining stub without causing callousing or swelling, especially in scar-prone species. This tool's concave blades expedite healing compared to straight cuts.

Crafted with spherical blades, the knuckle cutter combines strength and precision for a clean "biting action." Its unique shape swiftly removes stubs or knobs in a single stroke, leaving a hollow circular cut that promotes rapid healing with minimal scarring.

Beyond branch work, these knuckle cutters are versatile, making them ideal for refining root or trunk areas that are hard to reach with other tools. However, they require care when used on roots, as they are not as sturdy as dedicated root cutters.

Handcrafted by skilled Japanese artisans, our Kaneshin knuckle cutters come with a certificate of authenticity and are an essential tool for bonsai enthusiasts.
