Socket chisels are more difficult to make and tend to be more expensive to manufacture compared to the tanged type generally available. However, socket chisels are very strong and the handles less likely to break than a tang chisels. O-1 tool steel holds an edge much better at lower angles, 25° or less. This makes these chisels much more useful for paring or slicing tasks, where a more acute cutting angle works best. Lie-Nielsen produce five sizes in O-1 tool steel, each ground at 25°. They are all forged in the traditional socket style and fitted with polished Hornbeam handles. The sides are square and parallel with thin edges to give maximum access. The backs are ground flat and hand finished. Overall length: 230mm (9"), blade length 85mm (3.3/8"). Available as a set of 5 comprising sizes: 3.2mm(1/8"), 6.3mm(1/4"), 9.5mm(3/8"), 12.7mm(1/2") and 19mm(3/4"), comes with a soft leather tool roll.
