66, has a handle specially shaped to give control over its movements, and a long thin blade, which in the best form is beveled on the two edges to facilitate grooving.

It is intended only for steady pressure with the hand and not for use with a mallet.
The _framing-chisel_, Fig.

67, is thick and heavy and was formerly much used in house framing.

It is usually made with the handle fitting into a socket on the shank, in order to withstand the shock of heavy blows from the mallet.
The _mortise-chisel_, Fig.

68, is made abnormally thick to give the stiffness necessary for levering the waste out of mortises.
(2) Chisels are also named according to their shapes: as, skew-chisels, corner-chisels, round-nosed chisels, etc.
[Illustration: Fig.69.Paring with a Chisel.] The angle of the bevel of a chisel is determined by the kind of wood for which it is most used, hard wood requiring a wider angle than soft wood, in order to support the edge.
