As the name suggests, a spear point blade looks like the tip of a spear. The sharpened and unsharpened edges of the blade take on a more symmetrical shape, both approaching the point at a central axis. While most spear points have sharp edges on both sides, some blades have unsharpened backs with a short sharpened portion close to the tip. Spear point blades are more aggressive than drop point blades because of the double-sided sharpened edges. Variations of the spear point blade include the dagger and the needle. Dagger blades have longer parallel sharpened edges on both sides, and the symmetrical slope of both sides towards the point is narrower. Needle blades are similar to daggers, but they are thinner and narrower from the base up to the tip. Spear point blades permit cutting and slicing using both sides of the blade, but their piercing capabilities depend on how narrow their tips are.
