Emerson is one company that makes quality tactical knives. It is known among elite military and police agencies worldwide. Emerson knives are also available to private citizens. They are experts in the manufacture of tactical folding knives using the Walker Linerlock. It is a locking system that holds the knife in place with a leaf spring when it is in open position. This prevents the blade from closing when in use.

The most common models are the CQC-7, Commander, SARK, Karambit, Raven, and the SPECWAR. One of the features common to most Emerson knives is the Wave. It is a hook on the spine of the blade which when snagged on the edge of the pocket or sheath causes the knife blade to open as it is drawn. The Wave is a patented innovation of Emerson Company. Aside from folding knives, Emerson also manufactures a small variety of fixed blade knives.
