Stainless Steel Knob Cutter 190 mm
Stainless Steel Bonsai Knob Cutter
The Stainless Steel Bonsai Knob Cutter is a specialised pruning tool designed for the precise removal of knobs, burls, branch stubs, and protruding wood on bonsai trees. Its uniquely shaped, rounded cutting head allows it to scoop out wood cleanly, leaving a hollowed cut that heals naturally and smoothly over time.
Unlike standard concave branch cutters, the knob cutter is specifically intended for deeper, rounded cuts, making it ideal for refining trunk lines, removing unsightly swellings, and correcting growth defects during both early training and advanced refinement stages.
Key Features & Benefits
- Rounded cutting jaws designed to remove knobs, bumps, and branch stubs cleanly
- Creates deep, hollow cuts that promote smooth callus formation and minimal scarring
- Precision-ground stainless steel blades for durability, sharpness, and corrosion resistance
- High cutting strength, suitable for harder wood and dense growth
- Excellent control and accuracy for detailed structural work
Why Use a Knob Cutter?
A knob cutter is an essential tool for tasks where a standard concave cutter is not sufficient. It allows the artist to remove unwanted protrusions in a controlled manner, ensuring the wound closes evenly and blends naturally into the surrounding trunk or branch surface.
By creating a rounded recess, the knob cutter helps prevent raised scars and bulges, resulting in a more refined and natural appearance as the tree matures.
Knob Cutter vs Concave Cutter
- Knob cutters are designed for deep, rounded cuts and the removal of protruding wood or branch stubs
- Concave cutters are ideal for cleanly removing branches flush with the trunk or branch line
Many bonsai practitioners use both tools together, with the concave cutter for branch removal and the knob cutter for refinement and final shaping.
Ideal For
- Removing knobs, burls, and branch stubs
- Correcting swelling or uneven growth on trunks and branches
- Refinement work where minimal scarring is essential
- Intermediate to advanced bonsai training
