The IRWIN Marples MS500 Series All-Purpose Chisels with ProTouch Handle. These chisels have a large metal striking cap to withstand hammer impacts, prolong the life of the handle, and prevent mushrooming. ProTouch handles are designed to provide extra comfort, grip, and also reduces vibrations and reduces hand fatigue. One-piece blade forging gives added strength and durability. Made from special tool steel which ensures a much sharper cutting edge for quicker and easier operation. A special hardening process gives the blade a longer lasting edge - less time spent re-sharpening. The blade is hardened to the last inch giving more working chisel for your money. Every chisel is honed and sharpened ready for use out of the packet - to save you time and effort.
