Kobu Kiri Hasami – Spherical Knob Cutters

For those moments when brute strength must meet subtlety, Kobu Kiri Hasami—Japanese spherical knob cutters—offer the perfect balance. Designed for removing trunk knobs, thick roots, and heavy branch stubs, their spherical blades bite cleanly into wood, leaving a shallow, hollowed-out wound that promotes smooth, scar-free healing over time.

The name Kobu Kiri (瘤切) literally means “knot cutter” or “lump cutter,” a reference to the rounded bulges that often form at the base of branches or in dense root zones. These cutters excel at reducing or eliminating those growths without damaging surrounding bark or cambium.

Hand-forged in Japan from high-carbon steel, these cutters are strong enough to handle thick material and precise enough to use with confidence on high-value trees.

Note: Wipe clean and oil after use to prevent rust and extend the life of the blades.
