Introduction
Edged handtools are designed with sharp edges for working on metal, wood,
plastic, leather, cloth, glass, and other materials.
They are used to
remove portions from the work or to separate the work into sections by
cutting, punching, scraping, chiseling, filing, etc.
Most edged tools have hardened cutting edges or points and require extreme
caution when in use.
The tools covered in this task are those currently
issued by the Army Ordnance Supply System.
2.
Chisels
a. Purpose. Chisels are made to cut wood, metal, hard putty, and other
materials. Woodworker's chisels are used to pare off and cut wood. Cold
chisels are used to chip and cut cold metal. Some blacksmith's chisels are
used to cut hot metal. A special chisel is available to cut hard putty so
that glass may be removed from its frame channel.
