The Stanley FatMax® Thru tang bevel edge chisels have an ergonomic handle design incorporating a shatterproof polymer handle. The ergonomic soft grip longer handle is useful for maximum control, feels good in the hand and is comfortable in all applications. The friction welded bolster also gives strength and durability. The steel striking cap can be struck with a steel hammer for increased cutting force and the body resists most solvents. The ISO Standard Blade is made from high quality ball bearing grade steel EN31 and is fully ground and finished for ultimate sharpness and the full length blade guard provides added safety. This FatMax chisel range has a superior design - 50% stronger handle (than the old Dyna Grip Pro Chisel on side impact test) for extra reassurance and durability. The quality chrome alloy (ball bearing grade) steel provides superior edge retention
