Looking at the side view of a sword blade, distal taper can be uniform (where the taper is even from hilt to point), concave (tapering more sharply near the hilt and more gradually toward the point), or convex (gradual near the hilt and sharper toward the point). It could even be complex , for whatever reason the swordmaker made it that way. Each of these designs gives the blade different characteristics (for example, fast bladework would be easier with a concave distal taper).
