The CRKT F.T.W.S (For Those Who Serve) is an Allen Elishewitz design which is the culmination of two years of design work, and the finest tactical fixed blade CRKT has ever manufactured. SK5 carbon steel was chosen for the blade because of its strength and hardness. The tip is a modified spear point with full width near the tip for penetrating strength. The top of the blade features a four-inch-long flat grind with a chisel ground edge for heavy hacking and chopping tasks. This knife is a workhorse!
