Abstract

The blade is of I-cross section with each flange solidly cylindrical. The cutting end is ground to a point and the opposite end tapers down to a robust circular hammerable head. The top of the web adjacent the head is drilled facilitating hanging storage of the tool. The flanges reinforce the web to such an extent that the latter may be relatively thin allowing large savings in material cost and improved strength in comparison with conventional cold chisels which are rectangular in section.
