Mortise chisel
The mortise chisel is a wood chisel with one bevel and a neck. Its iron is
thicker than it is wide and usually tapers a bit at the wooden handle so
that it does not get stuck. There are different widths, about 0.1 to 2 cm.
The carpenter uses the chisel to cut out pinholes. The narrowest chisel
(1-3 mm) makes it possible to dig a groove or very narrow holes, for
example for a hinge (to be inserted). He is hit with the hammer. The turner
also uses a chisel, but without a neck, to make grooves. See also the hinge
chisel. [MOT]
