Bonsai branch cutters are specialist pruning tools designed to remove branches close to the trunk, creating a concave wound that heals cleanly and leaves minimal scarring. Unlike standard garden tools, their curved blades produce a hollow cut that encourages faster callusing and keeps the tree’s natural appearance intact.
Understanding how bonsai branch cutters work, which type you need, and how to choose the right pair can make a huge difference in your early results. Whether you’re just starting your bonsai journey or looking to upgrade your toolkit, this guide explains everything you need to know about branch cutters, from the different styles available to what makes a high-quality pair worth the investment.
For most beginners, a single 180mm concave cutter covers the majority of the branch work needed on a starter bonsai.
This guide covers how branch cutters work, how to choose the right size, and what to look for in terms of quality and build.
Branch cutters are designed specifically for removing branches close to the trunk. Their concave blades create a hollow wound rather than a flat cut, which calluses over faster and leaves less visible scarring than standard garden tools produce. For any structural branch work on a bonsai, they are the correct tool for the job.
The 180mm Bonsai Branch Cutter features concave blades that create clean cuts, promoting fast, smooth healing. Designed for branches up to 15mm thick, it’s durable and precise. Avoid cutting hard materials or twisting. Use diagonal cuts along fibres and the blade base for best results.
The 200mm Bonsai Branch Cutter features concave blades for clean cuts that heal quickly, ideal for branches up to 12mm thick. Made from durable, high-quality materials, it’s precise but brittle—avoid cutting hard materials or twisting. Use diagonal cuts along the fibres and the blade base.
Understanding the differences between various types of bonsai branch cutters helps beginners select tools that match their tree’s size and pruning needs.
The right branch cutters come down to three factors: size, steel quality, and handle comfort.
Size and branch thickness
Steel quality
Handle comfort
| Cutter | Best for | Branch thickness | Beginner friendly |
|---|---|---|---|
| 180mm concave | Small to medium trees, everyday pruning | Up to 15mm | Yes |
| 200mm concave | Larger trees, thicker branches | Up to 20mm | Yes, once basics are established |
| Branch splitter | Splitting large branches before removal | Thick branches only | Not essential for beginners |

For most beginners, a single 180mm concave cutter is all you need. In our experience, the most common mistake is either using general garden scissors for branch work or buying a larger cutter than the tree actually requires. Start with the 180mm, learn how your tree responds to pruning, and add to your toolkit from there.

Common questions about bonsai branch cutters, answered.
Yes, for any structural branch removal close to the trunk. Standard scissors cannot create the concave wound that branch cutters produce, meaning cuts heal more slowly and leave more visible scarring. For light leaf and shoot trimming, scissors are sufficient.
A 180mm concave cutter is the right starting point for most beginners. It handles branches up to 15mm thick, covering the majority of work needed on small to medium sized starter trees. The 200mm is worth considering for larger trees or thicker branches.
Concave cutters are a type of branch cutter. The blade curves inward to create a hollow wound rather than a flat cut, which heals faster and leaves less visible scarring. Most bonsai branch cutters sold today are concave cutters and the terms are often used interchangeably.
For leaf and shoot trimming, yes. For branch removal close to the trunk, no. Standard shears produce flat cuts that are harder to callus over, increasing the risk of visible scarring and slower healing.
Branch cutter is the general term. Concave cutter refers specifically to the blade shape, curved inward to create a hollow wound. Most bonsai branch cutters are concave cutters, and the terms are widely used interchangeably.
Position the concave face against the trunk and make a single clean cut without twisting. For thicker branches, cut diagonally along the wood grain using the blade base for maximum control. Apply cut paste to the wound afterwards to protect against disease and encourage faster healing.
Wipe the blades clean after every use, store in a dry environment, and apply camellia oil to the pivot point monthly. Sharpen every two to three months or when blades begin pulling rather than cutting cleanly. High-carbon steel cutters need more frequent oiling than stainless steel alternatives.
