The Black Abyssal Apparatus OTF is an automatic knife with a black zinc alloy handle. The switch is on the side which adds to the ease of single handed deployment of the blade. Upon pushing the switch up, a spear pointed, two tone black and satin finish blade springs from the top of the handle. This blade is stainless steel with two tone black and satin finish fit with a fuller with 4 holes along it to assist with balance and weight distribution. The Black Abyssal Apparatus OTF comes with a black nylon sheath.
