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.”
