TYPES AND USES - Continued
BLACKSMITH’S OR SLEDGE
HAMMERS
Blacksmith’s or sledge hammers are used for striking
punches and chisels, for breaking stones and concrete,
and for setting timbers. These hammers, although
similar to the machinist’s hammers, give the user the
advantage of a heavier head and a longer handle.
A cross peen hammer is used as a chisel for removing
rivet heads and for stretching or bending metal.
A double face sledge hammer has similar faces on both
sides of the head.
A straight peen hammer is used like the cross peen but
differs from the cross peen since its peening edge is
turned ninety degrees. This keeps the handle parallel to
the struck surface.
BUMPING BODY HAMMER
A bumping body hammer is used to straighten and form
metal.
The club hammer is a heavy double-faced demolition
hammer. It is primarily used to break up masonry.
Cross peen hammers have a broad flat face on one side
of the head and a peening chisel edge on the other side.
