In 2022 I filed an application for a patent for the Black Box concept knife. The idea of a fixed blade with part of the blade retracted in the handle is a concept I designed back in the late 90's which was put in production by Masters Of Defense called the Phoenix. That knife had a button lock mechanism. For this Black Box concept I took the idea of the Phoenix and completely re-designed the entire knife, from the shape, to the locking mechanism and the sheath. Then I found a manufacturer (Ketuo in China) who was able to produce these for me at the quality level that I wanted and an affordable price.
The concept allows the user to carry a 4" fixed blade with part of the blade retracted in the handle and only 1.5" exposed. The sheath holds onto the tip of the blade and as the knife is pulled out, it extends the blade. The patent pending mechanism locks the blade open. When the lock is disengaged the blade slides back in the handle and the knife can be put back in the sheath (it needs to be done in this order for a safer and trouble free re-holstering). The sheath features a clip which allows the user to secure it to garments and gear. The system allows the user to carry a 4" fixed blade in a compact package. The Ek version is the non ring version of the Black Box; this concept lends itself beautifully to the Ek design. If you are not familiar with the Ek brand, this knife company started by John Ek in 1942 produced combat knives for our servicemen and these knives have been present in many armed conflict since WWII.
4 different blade configuration are available: Dagger (no serration, partial serrations or full serrations) and single edge.
