Backlock

Folding knife with back lock ( above) and frame lock (below)

A backlock ( English lockback ) or rocker lock is a mechanism for locking the blade of lockable folding knives .

A long spring-loaded rocker is housed between the plates of the handle, the front end of which merges into a hook. This engages in a groove on the folding joint of the blade when it is fully opened. To unlock the blade, the hook must be lifted out of the groove by pressing the rear lever of the rocker down against the spring pressure. Usually it is exposed there through a recess in the rear end of the back handle.

There are variations where the lever is mounted in the middle or at the front on the back of the handle. To distinguish them, they are called mid lock and front lock in English .

With a few components, a backlock folding knife is particularly stable, but often relatively heavy, both hands are often required to fold it shut, and the overall artistic / ergonomic design of the handle is subject to restrictions.
