They are a very wicked looking dart, aren't they? Although they are heavy, with practice they can penetrate anything you're aiming to shoot.  An awesome dart in design and lethal for your hunt.  They are one of the heaviest darts made as they are made from a nail and hammered to a find point at the end much like a spear.  They have a 3/8" long tapered spear type-head.  They are available in 10 or 50 count for the .40 and .50 caliber blowguns only.
