Joshua Roth Root Cutters

High-carbon steel is significantly harder than standard stainless steel, allowing the blades to hold a razor-sharp edge much longer. This sharpness is essential for making clean, precise cuts through tough roots, which minimizes damage and encourages faster healing for your bonsai.

The 7 1/8-inch small cutter is ideal for delicate work on smaller bonsai specimens where maneuverability is key. The 10 3/4-inch large cutter offers greater leverage, making it the better choice for thicker, established root systems that require more force to cut cleanly.

Yes, sand-casting is a traditional method that creates a robust, dense tool structure. This results in a heavy-duty feel and exceptional durability, ensuring the cutters maintain their alignment and performance even after years of rigorous use.

Because they are made from high-carbon steel, these tools are susceptible to rust if left wet. Always wipe the blades clean and dry them thoroughly after each use, and apply a light coat of camellia oil or mineral oil before storing them to prevent oxidation.

While they are sharp enough to cut branches, they are specifically engineered for the unique density and soil-grit environment of root pruning. Using them on woody branches may dull the blades faster than intended, so it is best to keep them dedicated to root work.
