"The LFK uses a patent pending mechanism that swings a “ tail fin,” which is housed in the handle, out to cover the closed tip of the blade. A benefit to this new design allows users to have a knife that has a large blade while being collapsible into the pocket or sheath. Most other knives with such a large blade (5 . 20 inches) to handle (5 .05 inches) ratio are manufactured as fixed blades that require a sheath to protect the sharpened portion of the knife."
"The new tail fin mechanism rotates open and closed in tandem with the blade allowing for a smooth, one-handed operation. The handle is machined aluminum with a soft and tacky Santoprene® overmold. The 10100 LFK utilizes a locking liner and comes standard with a tip-down pocket carry clip. The blade steel is 440C , and the blade style is a highly versatile clip-point."
