Lie Nielsen Chisels are based on the Stanley 750 Bevel Edge Socket Chisels. Socket chisels are not common these days, perhaps because they are expensive to make, but Stanley and others once produced these chisels in a vast array. Socket chisel handles are less likely to break than tang chisels, and can be replaced easily. At 9" long, these chisels are particularly comfortable in the hand and have excellent balance.
Made of A-2 Tool Steel, hardened to Rockwell 60-62, cryogenically treated and double tempered.
The edges are square, parallel along the length, and very narrow so you can get into tight places. The backs are ground flat and finished by hand at 400 grit. The bevel is flat ground at 30°, but a higher secondary bevel (about 35°) is advisable, depending on the wood and how the chisel is being used. Additional honing is recommended.
Lie-Nielsen Chisels have Maine-harvested Hornbeam handles. Hornbeam, also known as Ironwood, was once prized for its toughness, but usually winds up as firewood these days. This under-utilized species makes superb chisel handles.
