Hacking knife

Hacking or side knives are heavyweight knives.

They are strongly constructed with a single-sided straight edge. The back of the blade is exposed for hammering on. This back edge is intended to be hit with a steel hammer, not a wooden mallet or club. The handle is a solid steel through tang, with side scales. The scales are often of thick leather, to absorb shocks.

Their typical uses are either for glazier's work, or else as a light froe for splitting timber.
