The TOPS S-455 XcEST-Delta Folder Knife Black Plain folder is based on the the success of the original XcEST-Alpha (fixed blade) from TOPS Knives. This folding knife is built like a tank! It has a 3/16" thick N690Co steel blade that is black coated and sports ambidextrous thumb studs. The mega-tough handle has a 6061-T6 aircraft aluminum frame with a steel liner lock tab and black/blue layered G-10 scales. The handle features a divot on both sides for use with a bow drill. The XcEST-Delta has a steel pocket clip for tip-up carry and includes a black ballistic nylon sheath that can be mounted horizontally or vertically on a belt (MOLLE compatible).
