170mm Bonsai Branch Cutter – Concave / Side Cutter Tool
Shape and refine your bonsai with confidence using the 170mm bonsai branch cutter. Also known as a concave cutter or side cutter, this high quality tool is designed to remove branches cleanly while supporting the long-term health and appearance of your tree. It is ideal for cutting branches up to approximately 10mm thick, making it suitable for most bonsai trees.
This size offers excellent control and ease of use, which makes it a great choice for both beginners and more experienced enthusiasts. Whether you are carrying out structural pruning or fine styling work, this tool allows you to make precise cuts with minimal effort. As a result, you can shape your bonsai more accurately and safely.
Clean Cuts for Better Healing
The key benefit of a concave branch cutter is the type of cut it creates. Instead of leaving a flat or raised wound, this tool produces a slightly hollow, concave cut. This is important because it allows the tree to heal flush with the trunk over time. In contrast, using standard scissors or a saw can leave a visible lump, which may lead to unattractive scarring.
By creating a cleaner finish, these cutters help your bonsai heal more naturally and maintain a smooth, refined appearance. This makes them an essential tool for anyone serious about bonsai styling and long-term care.
Versatile and Practical Size
At 170mm, this cutter is well suited to most bonsai tasks. It offers a good balance between strength and precision, allowing you to handle a wide range of branches with ease.
