2-3. Sharp-Edged Cutting Tools. Chisels are considered sharpedged
cutting tools. The chisel is an indispensable tool and is often the
most abused. It should be used solely for cutting wood surfaces. It
should never be used for prying or as a screwdriver. A chisel is a
flat piece of steel (of varying thicknesses and widths) with one end
ground to an acute bevel to form a cutting edge.
a. Types of SharpEdged Cutting Tools.
(1) Paring Chisel. A paring chisel (Figure 217) is used for
shaping and preparing large surfaces. It is used with a steady
sustained pressure of the hand and should never be driven with a
mallet.
Figure 2-17.

(2) Firmer Chisel. The firmer chisel (Figure 218) is more
substantial tool than the paring chisel. It is usually used for
routine work, but may be used for paring or light mortising. When
paring, drive the chisel by hand pressure. For light mortising, use
a mallet.

CAUTION
Never use a hammer or metal tool to drive a chisel-use wood
to wood.
This will help preserve the handles of your
chisels.
