A cutting edge for a ground engaging machine, the cutting edge comprising:
- a top side;
- a bottom side opposite the top side;
- a front side extending between the top side and bottom side;
- a back side opposite the front side, the back side extending between the top side and the bottom side;
- a first side extending between the top side and the bottom side and extending between the front side and the back side;
- a second side opposite the first side, the second side extending between the top side and the bottom side and extending between the front side and the back side;
- and
- a plurality of insert apertures along the bottom side, each of the plurality of insert apertures having a diameter, the plurality of insert apertures arranged as at least a first row and a second row, each row including a plurality of the plurality of insert apertures and extending from adjacent the first side to adjacent the second side, the first row of the plurality of insert apertures spaced less than the diameter of one of the plurality of insert apertures from the second row of the plurality of insert apertures, the plurality of insert apertures spaced from the front side, the back side, the first side, and the second side.
