Lie-Nielsen chisels are made of A-2 Tool Steel, hardened to Rockwell 60-62, cryogenically treated, and double tempered.
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. We don’t recommend using a 16-ounce framing hammer with these chisels, though that is how we test them.
