About Wood and Plastic Trowel Handles

Trowel handles can be made from wood or plastic. Wood handles are turned on a lathe from hardwoods like beech, maple, hickory, ash, and gumwood. Woods are chosen for their resistance to checking, splintering, and splitting. Top quality and ceremonial trowels may have wood handles wrapped with leather or mahogany or other tropical wood. Possible factory finishes for trowel handles include shellac, lacquer, and urethane, depending on the trowel's age.

One way to identify older trowels is by the amount of work needed to turn the handle. Earlier trowels may have a distinctive shape and one or more decorative rings. Later trowels have smooth handles with a simple profile. Some mid-20th century American trowels had the maker's name stamped in the handle (Rose) or ferrule (Disston).

Plastic trowel handles have been made for at least 50 years. Tenite is an Eastman trademark* for cellulose acetate butyrate, which dates to 1938. Goldblatt, Marshalltown, and W. Rose have all used cellulose acetate butyrate for brick trowel handles. Alcohol and petroleum solvents will degrade cellulose acetate butyrate.

Other composite handles use plastic and synthetic rubber, including a red acrylic Marshalltown handle.

Major US trowel manufacturers sell replacement wood and plastic handles.

*Quote from Eastman: “Tenite cellulosic plastics are noted for their good balance of properties - toughness, hardness, strength, surface gloss, clarity, and a warm feel. Tenite cellulosic plastics are available in natural, clear, selected ambers or smoke transparents and black translucent.”
