A trowel is one of several similar hand tools used for digging, smoothing, or otherwise moving around small amounts of viscous or particulate material.
In gardening, a trowel is a tool with a pointed, scoop-shaped metal blade and a handle. It is used for breaking up earth, digging small holes, especially for planting and weeding, mixing in fertilizer or other additives, and transferring plants to pots.
A cathole trowel is similar to a gardening trowel, but it was specifically designed for digging catholes in the backcountry. Cathole trowels are used by backpackers, hikers and some kinds of campers, so they are often made of lighter weight materials than gardening trowels to make them easier to carry. Also, they may have features such as ruled sides to measure for proper cathole depth or jagged edges for cutting through roots or frozen soil. Some cathole trowels are also designed to fold-up or collapse into a smaller size for easier storage.
A bricklayer's trowel (also known as a masonry trowel or pointing trowel) is a 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 mould. A tuck pointing trowel is longer and thinner, designed for packing mortar between bricks. Brick trowels are traditionally made of carbon steel, but some newer versions are made of cast stainless steel, which has longer wear and is rust-free.
In archaeology brick or pointing trowels (usually 4" or 5" steel trowels) are used to scratch the strata in an excavation and allow the colours of the soil to be clear, so that the different strata can be identified, processed and excavated. In the United States, there are several preferred brands of pointing trowels Marshalltown being one, but in the British Isles the WHS 4" pointing trowel is the traditional tool.
Several types of trowel are used in concrete construction. The float trowel or finishing trowel is usually rectangular, used to smooth, level, or texture the top layer of hardening concrete. A flooring trowel has one rectangular end and one pointed end, made to fit corners.
A gauging trowel has a rounded tip, used to mix measured proportions of the ingredients for quick set plaster.
A power trowel is a type of Light Construction Equipment, used by construction companies and contractors, serving as a finishing equipment for concrete works.
The trowel is the nearest that the archaeological profession has to a uniform symbol. It is incorporated into the designs of many archaeological association logos and publications.
