Shape Identification

Yes, there is, shown above.

The shape appears similar to the tip of a wedge or flat-head screwdriver. The object shown was created in a 3d modeling program as the intersection of two shapes: a cylinder and a triangular prism.

A cylinder appears to be a circle from above, and a square from the side (if its height is equal to its diameter). By intersecting it with a triangular prism, it takes on a triangular appearance from the third direction.
