There are specialist tools without which certain jobs would be nigh on impossible. Take the humble looking drawer lock chisel. This pair of chisels is indispensable for cutting small mortices in tight places. They take their name from cutting the mortice to accommodate the bolt of a drawer lock. Produced in O-1 tool steel the Lie-Nielsen version is a vastly improved design over the traditional. The cutting edges are at 90° to the shaft with one edge at right angles to the other. There is a flat behind each blade for a hammer blow. The pair comprises a left and right-handed chisel. Precision ground, 100mm overall length, blade widths are 12.7mm and 6.35mm, blade length is 25mm.
