Know before you buy
These cutters are specifically designed with a long, slender profile that allows you to reach deep into the root ball and navigate tight spaces directly beneath the trunk base. Their bypass cutting mechanism ensures a clean, flush cut that promotes faster healing compared to the crushing action of standard anvil pruners.
At 10.6 inches long, these are substantial tools designed for leverage. While they are ambidextrous, users with smaller hands may find the handle spread requires a two-handed grip when tackling particularly thick or stubborn roots.
High carbon steel is prized for its edge retention but is prone to rust if left wet. After each use, wipe the blades clean, remove any sap with a solvent, and apply a light coat of camellia or mineral oil before storing them in a dry place.
Yes, the blades are designed to be sharpened. Because they are made of high carbon steel, you can maintain the edge using a sharpening stone or a diamond file to ensure they continue to make clean, precise cuts over many years of use.
Bonsai root cutters are built for heavy-duty, deliberate work rather than repetitive pruning. The lack of a spring allows for greater control and prevents accidental closing, ensuring you can position the blades exactly where needed before applying the necessary force to cut through dense, woody roots.
