The IRWIN Marples M444 Series Blue Chip Bevel Edge chisels have high impact round blue plastic handles, contoured for maximum control, radiused for a comfortable grip and have been designed for use with a mallet and will absorb the occasional hammer blow. The solid one-piece forged bolster fitted bevel edged blades are manufactured from the best in category carbon steel, tempered along the full length of the blade and hardened up to the last 25mm for a longer working life and annealed for an edge that is slow to blunt yet easy to sharpen.Siz1 X Marples M444 Series Blue Chip Bevel Edge Chisel 38mm (1 1/2in).
