The Marshalltown 1 1/2" Chisel Knife with Rosewood Handle (Model: M7152, Item ID: 15072) is a professional-grade putty knife designed for durability and precision in drywall, plastering, and woodworking applications. The blade is heat-treated, hardened, tempered, and annealed to ensure consistent hardness and long-lasting performance. It features a full tang construction that extends through the handle for superior strength and balance. The handle is made from laminated rosewood that is resin-impregnated, offering resistance to chemicals, solvents, and moisture. This enhances longevity and provides a comfortable, weighted grip that reduces hand fatigue during extended use.
