Blades tighten up solidly in both opened and folded position through the use of locking lugs on the blades to lock blades in place and a wing nut to loosen and tighten. Fast deployment from folded to ready to use. Original Cobray nylon leather tipped sheath has a loop for easy belt carry. This throwing knife was designed to be very easy to throw by anyone and the size and weight of the knife make it very effective. Pretty much if you can throw a baseball you can throw this knife. Only the ends of the blade are sharpened. The straight part of the blade is not sharp to allow for throwing grip. The knives were made to be a utilitarian survival tool with the angle of the grind on the sharpened tips designed to allow the user to sharpen a dull tip with a simple file or similar tool in a survival situation. Excellent Condition.
