prying, and for lifting. They are also used extensively for
dismantling buildings, crates, boxes, and other wood products. They
include nail pullers and wrecking bars.
a. Nail Pullers. Nail pullers (Figure 253) are used for
removing nails, especially those that are driven flush or below the
surface of wood. A nail puller
has two jaws that set over the
nailhead. Pressure is applied
by a series of bows from the
sleeve. The sleeve, which fits
over the handle and slides up
and down, is usually equipped
with a guard to protect your
hand from the sliding sleeve.
The average length of a nail

puller is 18 inches.
b. Wrecking Bars. Wrecking bars are usually made of forged,
tempered steel. They are hexagonal in shape, with a curved, slotted
neck for pulling large nails. The average length is 24 to 36 inches.
They are used to dismantle and tear down wooden structures. A bar of
the same type without a curved neck is called a pinch bar. It use is
similar to that of a wrecking bar. Figure 254 shows the types of
wrecking bars.
