The Barr Timber Framing Chisel is a hand-forged socket framing chisel from Idaho, in 1, 1-1/2 and 2 in widths, with a replacement handle sold separately.
The flat of the blade is 7 in long and at least 5/16 in thick over most of its length, and the chisel is 18 in overall. After forging, each tool is annealed, quenched and tempered, then fitted with a hardwood handle that seats in the socket, with a steel shock ring on top to help keep it from splitting under the mallet. If you finally wear a handle out, the replacement drops right in.
Barr Specialty Tools is run by Barr Quarton and his son, Jess, in Idaho, and every tool is hand forged. Barr has worked with tool steel since 1977. His first tool was a slick, which went on to win best in show at a Timber Framers Guild show.
