Know before you buy
While a concave cutter is used to remove branches, a knob cutter features a rounded, spherical blade design specifically intended to gouge out the woody knobs left behind after pruning. This allows the wound to heal inward, resulting in a smooth, flush surface rather than a protruding scar.
Yes, the tool is crafted from high-quality stainless steel, which offers excellent resistance to rust and corrosion. This makes it easier to maintain, especially when working with moist soil or sap-heavy branches.
Absolutely. The Roshi Tools knob cutter is designed with an ambidextrous build, ensuring comfortable and precise operation regardless of your dominant hand.
The 170 mm length is optimized for balance and leverage, providing enough force to cut through tough woody growth while remaining compact enough for the intricate, detailed work required in bonsai cultivation.
No, this model does not feature a spring. This design choice is common in professional-grade bonsai tools, as it gives the user complete control over the cutting pressure and blade closure speed.
To keep the blades in top condition, wipe them clean of sap and debris after every use using a soft cloth. Periodically applying a light coat of camellia oil will help protect the steel and keep the pivot point moving smoothly.
