The francisca is characterised by its distinctly arch-shaped head, widening toward the cutting edge and terminating in a prominent point at both the upper and lower corners.
The top of the head is usually either S-shaped or convex with the lower portion curving inward and forming an elbow with the short wooden haft.
Most franciscas have a round or teardrop-shaped eye designed to fit the tapered haft, similar to Viking axes.
The tomahawk, a similar New World throwing weapon, experienced some influence by the francisca in the French territories.
The Nzappa zap is a weapon from the Democratic Republic of the Congo that is one of the more unusual-looking throwing axes.
