Kaneshin Bonsai Root Cutter

While these are engineered specifically for root pruning, they are capable of handling small branches up to 5mm in diameter. However, because the blades are designed for the density of root systems, you may find standard bonsai shears more comfortable for frequent, light foliage trimming.

Carbon steel offers exceptional sharpness and durability, but it is susceptible to rust if left wet. After each use, wipe the blades clean with a soft cloth and apply a light coating of camellia oil or a similar rust-preventative oil before storing them in a dry place.

The Kaneshin root cutter is rated for a maximum cutting capacity of 5mm. Attempting to cut material thicker than this can stress the pivot point and potentially damage the blades.

The extended handle design is intentional; it provides the extra leverage needed to slice cleanly through dense, woody root systems without requiring excessive hand force. This design helps reduce fatigue during long repotting sessions.

This is a professional-grade tool, but its straightforward design makes it an excellent investment for any bonsai enthusiast. If you are serious about root health and repotting, the precision and longevity of this handmade Japanese steel will serve you well regardless of your experience level.
