This Stanley Fat Max chisel is designed for robust masonry and tile joint work. Its blade, forged from one-piece chrome vanadium steel, undergoes hardening, quenching, and tempering, ensuring strength and longevity even under frequent use. A standout feature is the bi-material hand guard, which offers both comfort and protection from overstrike. The distinct modified parabolic striking end significantly reduces the risk of mushrooming and chipping, helping the tool maintain its effectiveness over time.
