Suwada Stainless Steel Bonsai Knob Cutter

A traditional tool to help cut branches in a way that allows the bonsai to heal faster. A knob cutter is not ideal to use for removing a whole branch at the trunk.

Using a spherical cut, this peculiar cutter makes a big difference in the way a bonsai looks as well as its recovery time. When we cut off a branch of a bonsai tree, the scar will appear like a lump on its trunk once it has healed. Cutting a little further in with a knob cutter ensures that the healed trunk will look flat.

In terms of sizes, a big knob cutter will save you some time and it will make a clean cut. A small one is suited to smaller branches and is easier to use to chew away any exposed parts of the main cut.

Suwada's knob cutter has been the preferred tool for Japanese bonsai growers for more than 70 years. The head is designed to cut small branches and clean the surface of a branch cut near the trunk.

Hand-forged, shaped, and polished. The master blacksmith in Suwada Open Factory takes pride in making the best bonsai tools as precise and ergonomic as possible.

Available in two sizes, and packed inside a traditional box, this is a perfect tool for anyone interested in starting to train bonsai trees.

Made to last long, using rustproof Japanese high carbon stainless steel.

All our products are made by artisans in Suwada Open Factory, in Niigata, Japan. The factory is open to the public without reservations to ensure transparency for all our claims.

In rare cases we collaborate with local companies to promote a product that we think you will love. In those cases we ensure that the companies adhere 100% to our highest standards of employee work conditions and traditional methods for crafting goods.

Once an object is made in Suwada, it is taken through extensive testing to ensure quality and durability. We hold the highest quality control standards possible, checking all items, one by one.

Craftsmanship is at the core of our model, and we make sure our craftspeople have great lives, high salaries and are able to expand their knowledge in their field when they wish to do so. This approach of continuous learning has pushed traditional crafts to a whole new level, and has permitted Suwada to train a new generation of men and women in Japanese metal crafts. We absolutely oppose machine made goods that can be made better by hand, and poor working conditions that treat people as if they are product making machines.

Our prices reflect humanist ideals. When you buy Suwada, you buy quality. You support vibrant communities of craftspeople, who design and make useful and beautiful objects, that will improve your everyday life, and carry a little of their maker's spirit in them. When you buy Suwada, you reaffirm all humanist values and virtues, and you chose unique over common.
