Abstract
A trowel handle having a blade, one or more upright supports mounted on that blade and a handle adapted for detachably engaging that support is disclosed. The handle includes a channel having tapered sidewalls configured to form a wedge-like engagement with a respective support, thereby precluding the handle's displacement relative to the blade absent the imposition of a force of considerable magnitude directed in a preselected direction.
