The Sonic Banshee Speed Assist Knife features a Karabiner (or carabiner) hook on the tail end allowing for fast action to and from rest. This feature is also excellent for keeping the knife securely on you and essentially will never become lost or fall out of your pocket like most knives. The blade is heat treated stainless steel with a satin finish and very sharp edge. The knives profile is strait back, yet this Sonic Banshee Speed Assist Knife features a false upper edge that goes almost the entire length of the blade. The frame is entirely steel, very durable, and has a black finish. Rubberized grips were added that feature a randomized camo pattern print.
