Claim:
1. A wear member for an earth-working implement, the wear member comprising: a body having front, rear, top, bottom, inner side and outer side portions; a front bottom edge defined along at least a portion of a front bottom interface between the front portion and the bottom portion, the front bottom edge aligned with a longitudinal axis; a front top edge defined along at least a portion of a front top interface between the front portion and the top portion, the front top edge aligned with the longitudinal axis; a front inner side edge defined along at least a portion of a front inner side interface between the inner side portion and the front portion; a front outer side edge defined along at least a portion of a front outer side interface between the outer side portion and the front portion; a front face defined on the front portion, the front face extending between the front inner side edge, the front outer side edge, the front top edge, and the front bottom edge; a front lower cutout edge disposed on the front face between the front bottom edge and the front top edge, the front lower cutout edge substantially parallel to the front bottom edge; a front cutout formed in the front face and delimited by the front lower cutout edge and the front top edge; a front lower surface defined on the front face between the front bottom edge and the front lower cutout edge; and a front cutout surface defined by the front cutout between the front lower cutout edge and the front top edge, the front lower surface being substantially parallel to at least a portion of the front cutout surface; wherein the body is configured to be mounted to a mounting edge of the earth-working implement such that the front face faces a direction away from the earth-working implement; and wherein: the front cutout surface further comprises: a transition seam formed between the front lower cutout edge and the front top edge; a front transition cutout portion defined between the transition seam and the front lower cutout edge, and a front base cutout portion defined between the transition seam and the front top edge; wherein the front base cutout portion is substantially parallel to the front lower surface; and the front inner side edge includes: an inner lower front portion defined adjacent the front lower surface along the front inner side interface between the inner side portion and the front portion, the inner lower front portion being aligned with a lateral axis defined perpendicular to the longitudinal axis; and the body further comprises; a rear bottom edge defined along at least a portion of a rear bottom interface between the bottom portion and the rear portion, the rear bottom edge substantially aligned with the longitudinal axis; a rear top edge defined along at least a portion of a rear top interface between the top portion and the rear portion, the rear top edge substantially aligned with the longitudinal axis; a rear inner side edge defined along at least a portion of a rear inner side interface between the inner side portion and the rear portion; a rear outer side edge defined along at least a portion of a rear outer side interface between the outer side portion and the rear portion; and a rear face defined on the rear portion, the rear face extending between the rear inner side edge, the rear outer side edge, the rear top edge, and the rear bottom edge; a rear lower cutout edge disposed between the rear bottom edge and the rear top edge, and a rear cutout formed in the rear face and delimited by the rear lower cutout edge and the rear top edge a rear cutout formed in the rear face; and wherein: the rear face further comprises: a rear lower surface defined between the rear bottom edge and the rear lower cutout edge, and a rear cutout surface defined by the rear cutout between the rear lower cutout edge and the rear top edge a rear cutout surface defined by the rear cutout between the rear lower cutout edge and the rear top edge and the rear cutout surface includes: a rear transition cutout portion and a rear base cutout portion, the rear base cutout portion being substantially flat and substantially parallel to the front base cutout portion; and wherein the rear lower surface is substantially parallel to the front lower surface; and wherein a normal axis is defined perpendicular to both the lateral axis and the longitudinal axis, and wherein a ratio between a body thickness, measured along the normal axis between the front lower surface and the rear lower surface, and a cutout thickness, measured along the normal axis between the front base cutout portion and the rear base cutout portion, is in a range greater than 1:1 and less than or equal to about 3:2.
