Tinyroots Carbon Steel Root / Knob Cutters. Advanced Tool

The knob cutter is very similar to the concave cutter but has several unique capabilities.

The cutting blades of the knob cutter are shaped somewhat like two halves of a sphere coming together. The shape allows the tool to aggressively bite into wood.

Protruding stubs are easily and quickly nibbled away by the knob cutter in a controlled fashion. It can remove lots of wood quickly yet is precise enough to shape the final surface cut on the trunk or branch.

An additional use of the knob cutter is the removal of undesirable root or trunk material in the area of a partially removed tap root. The aggressive nibbling ability readily removes excess callous underneath the trunk where lack of space makes it difficult to use other tools.

No other tool is as effective and clean in performing this task which is often necessary to properly fitting the bonsai into the pot.

Carbon Steel Dimensions: 210 mm

We ship thousands of bonsai trees and supplies each year, and every order is packed with care by our team. Live trees are watered, secured, and packaged to help them arrive safely and ready for their new home.

Live bonsai trees generally ship early in the week, Monday and Tuesday, to reduce time in transit. Tools, pots, soil, fertilizer, and other non-living items usually ship throughout the week.

Bonsai Outlet is a licensed nursery, not just a warehouse. We follow the proper inspection and certification requirements for shipping live plants across state lines. When a state requires additional documentation, such as a nematode certificate or nursery inspection certificate, we work to ensure the proper requirements are met before shipping.
