Wallis's conical edge is a ruled surface given by the parametric equations:

where a, b and c are constants.

Wallis's conical edge is also a kind of right conoid.

Figure 2 shows that the Wallis's conical edge is generated by a moving line.

Wallis's conical edge is named after the English mathematician John Wallis, who was one of the first to use Cartesian methods to study conic sections.^[1]
