Abstract
A (modular wall block is adapted for being assembled together with a number of like blocks in stacked courses to form a retaining wall. The wall block includes a front face and rear, top and bottom, and opposing sides. A locking shear key extends outwardly from either of the top or bottom of the wall block, and is adapted for residing between respective adjacent sides of like blocks in an adjacent upper or lower course to anchor the wall block in position. A severable area is formed with the shear key for being removed to accommodate placement and orientation of the wall block between respective adjacent sides of like blocks in an adjacent upper or lower course.

A modular wall block adapted for being assembled together with a number of like blocks in stacked courses to form a retaining wall, said wall block comprising:
- (a) a front face and rear, top and bottom, and opposing sides, the opposing sides tapering inwardly from the front face to the rear and defining respective engagement areas extending along generally straight and continuous edge portions of said block;
- (b) a locking shear key extending outwardly from at least one of the top and bottom of said wall block, and spaced inwardly from said opposing sides, front face, and rear of said block, said shear key adapted for residing between and engaging respective adjacent engagement areas of like blocks in an adjacent upper or lower course to anchor said wall block in position;
- and
- (c) wherein said shear key defines respective end edges each being formed generally parallel to a far engagement area of said block.
A retaining wall constructed of an assembly of like modular wall blocks arranged in stacked courses, each of said wall blocks comprising:
- (a) a front face and rear, top and bottom, and opposing sides, the opposing sides tapering inwardly from the front face to the rear and defining respective engagement areas extending along generally straight and continuous edge portions of said block;
- (b) a locking shear key extending outwardly from one of the top and bottom of said wall block, and spaced inwardly from said opposing sides, front face, and rear of said block, said shear key adapted for residing between and engaging respective adjacent engagement areas of like blocks in an adjacent upper or lower course to anchor said wall block in position;
- and
