Circa - Mid to Late 1990's BA5: BLACK ARMORHIDE TYPE 5 : "SURVIVAL"; POWDER COATED; 440C STEEL; STRAIGHT; 8 TEETH/IN. BLACK COATED BLADE; VERTICAL 1 & 2 LOGOS Sometime after the adoption of stainless steel blades, Gerber began offering, to the general public, the Mark II with a black coating on the blade. The coating was probably the result of requests for a blade that would not reflect light.
There were also rumors that prior availability of the coating was restricted to law enforcement personnel. I can find no record of this restriction, but it could have just been a Gerber policy. The BA5 knife is similar to the BA4 with a black handle and straight 8 TPI partially serrated blade but the blade is coated with a baked on smooth, non-reflective black coating similar to Gun-Kote.
