Abstract
A dipper lip includes a first side wing, a second side wing, a rear attachment portion that spans from the first side wing and the second side wing, and a front shovel portion that extends from the first side wing to the second side wing, and the front shovel portion defines a top shovel surface, while the rear attachment portion forms a top rear surface. The top shovel surface forms an obtuse angle with the top rear surface in a midplane of the dipper lip.

A dipper lip, comprising:
- a first side wing;
- a second side wing;
- a rear attachment portion that spans from the first side wing to the second side wing;
- and
- a front shovel portion that extends from the first side wing to the second side wing;
- wherein:
