Bonsai Aesthetics Novice Grade Root Cutter 7"
There are two good reasons why you might want to use one set of tools for root pruning and another for top pruning.

Designed and built strong enough for even the toughest old roots, they are very helpful if you plan on transplanting older bonsai trees.
