Japanese (Yoshiaki) Concave Cutters

There is no substitute for a concave branch cutter. This tool allows you to prune your bonsai tree while minimizing damage and speeds healing time. As it's name suggests, it leaves a concave cut and leaves a smooth finish allowing your tree's finish to blend in with the rest of the bark. Use Concave cutters to remove branches, nubs, etc.  

There are some bonsai plants that you do not want to use a concave cutter with - or use carefully. These include Mini Jades (Portulacaria afra) and Hawaiian Umbrella (Arbricolola) as when you cut into these tree, the area cut dies back. For these trees, it's often best to use shears when possible. 

The 8" Yoshiaki Carbon Steel Concave Cutter is a very popular tool that's the perfect combination of precision and power.

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.
