Any seasoned outdoorsman will always carry a reliable knife when hitting the wilderness, and so should you. Now, imagine how awesome it would be if your blade came with some vital built-in tools! Enter the TUSK Universal Survival Knife ($160).
Crafted out of heat-treated, top notch 440c stainless steel, TUSK is 12″ long and 0.20″ thick, offering a perfect balance between strength, hardness (~58 HRC) and wear resistance. After being laser cut, the blade is hand sharpened and polished to achieve a mirror-like finish, and rounded edges in the finger choil and the handle (made of durable black linen Micarta). Now for the coolest part: When you remove the handle (with an included hex key), you can access various tools, such as a 9 Hex wrench set, spear holes and notches, 1/4″ square & bit drive socket, and a 5 inch ruler.
Even better, the TUSK knife comes with a leather or Kydex sheath, fire starter, sharpening stone, and some Paracord, so you should be ready for any survival situation. Made by professional artisans in Spain, with lifetime warranty. Details in the video
