This Smith & Wesson SW8 Survival Knife is the perfect knife for outdoor enthusiasts. It can be used for the same applications as other hard-use knives, but it packs a secret surprise. The handle screws off to reveal a hollow cavity for spear attachment. No need to carry an entire spear when you can attach it to any sapling you can find in the woods and you've got yourself an adequate survival spear. Keep it close by your side with the included sheath.
