A trowel is one of several similar hand tools.
In gardening, a trowel is a tool with a pointed, scoop-shaped metal blade and a handle. It is used for breaking up earth and for digging small holes, especially for planting and weeding.
A bricklayer's trowel is a flat-bladed tool with a handle and flat metal blade, used by masons for leveling, spreading, or shaping substances such as cement, plaster, or mortar, as well as for breaking bricks to shape them or smoothing a mold.
A pool trowel is a flat-bladed tool with rounded ends used to apply viscous or particulate material coatings to concrete, especially on pool decks.
A flat-bladed trowel is the standard tool in archaeology. In the United States, the Marshalltown trowel is favoured and in the British Isles, the WHS 4" pointing trowel is the traditional tool.
The trowel is an important symbol in Freemasonry.
The pointing trowel is the primary tool used in archaeological excavation. For a history of the Sheffield made WHS trowel, see http://www.shef.ac.uk/assem/2/2trowel2.html for a history.
