Bonsai Aesthetics Novice Grade Root Cutter - 7"

There are a couple good reasons to use one set of tools for root pruning and another for top pruning: first to protect your top pruning tools from harsh soil particles; and second because tough, fibrous bonsai roots require more powerful tools. Root cutters are designed and built strong enough for even the toughest old roots, particularly those just below the base of the trunk.
