The MHG Firmer Bench Chisel is a German bench chisel in 24 widths from 2 to 60 mm: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 25, 26, 28, 30, 32, 35, 38, 40, 45, 50, 55 and 60 mm, plus a set of six in a box.
The blades are ground but deliberately not polished, which keeps the back flat instead of rounding it. Length scales with width: the 6 mm is 245 mm overall and the 26 mm is 275 mm. The handle is slightly flattened so the chisels don't roll off the bench. If your framing chisels live in the timber pile, these are for the joinery, furniture and finish work that comes after the frame goes up.
MHG Messerschmidt is a family-owned chisel maker in Schmalkalden, Germany, a town known for toolmaking and cutlery since the Middle Ages.
