A blade for use with an acetabular cup remover, the blade including: a body, the body having: opposed inner and outer surfaces; the inner surface being suitable to be directed towards the acetabular cup against which the blade is intended to be placed; proximal and distal ends; sides that extend between the ends; a longitudinal axis that extends between the proximal and distal ends; a longitudinal center plane that extends through the longitudinal axis; and a lateral axis that extends between the sides; a coupling feature (140, 294) attached to the proximal end of the body that cooperates with a complementary coupling feature (42, 90) of the acetabular cup remover so as to removably hold the blade to the acetabular cup remover; and teeth that project forward of the distal end of the blade body, each tooth having: an outer surface adjacent the blade body outer surface; an inner surface adjacent the blade body inner surface; a rake surface; a clearance surface and a cutting edge, wherein at least a plurality of teeth are further defined so that the rake surfaces and the clearance surfaces of the teeth meet to define cutting edges and wherein there is a plurality of teeth on each side of the longitudinal center plane of the blade body, characterized in that: the blade body is formed so that both the longitudinal axis and the lateral axis of the blade body are curved so that the teeth are arranged in a first curve that extends proximally to distally and a second curve that extends between the opposed sides of the blade body; and said teeth are formed so that on each side of the longitudinal center plane of the blade body there is at least one tooth (190b-190i) that has a rake surface that is located on an axis that, extending from the outer surface of the tooth to the inner surface of the tooth, is angled relative to the longitudinal center plane of the blade body. a body, the body having: opposed inner and outer surfaces; the inner surface being suitable to be directed towards the acetabular cup against which the blade is intended to be placed; proximal and distal ends; sides that extend between the ends; a longitudinal axis that extends between the proximal and distal ends; a longitudinal center plane that extends through the longitudinal axis; and a lateral axis that extends between the sides; a coupling feature (140, 294) attached to the proximal end of the body that cooperates with a complementary coupling feature (42, 90) of the acetabular cup remover so as to removably hold the blade to the acetabular cup remover; and teeth that project forward of the distal end of the blade body, each tooth having: an outer surface adjacent the blade body outer surface; an inner surface adjacent the blade body inner surface; a rake surface; a clearance surface and a cutting edge, wherein at least a plurality of teeth are further defined so that the rake surfaces and the clearance surfaces of the teeth meet to define cutting edges and wherein there is a plurality of teeth on each side of the longitudinal center plane of the blade body, characterized in that: the blade body is formed so that both the longitudinal axis and the lateral axis of the blade body are curved so that the teeth are arranged in a first curve that extends proximally to distally and a second curve that extends between the opposed sides of the blade body; and said teeth are formed so that on each side of the longitudinal center plane of the blade body there is at least one tooth (190b-190i) that has a rake surface that is located on an axis that, extending from the outer surface of the tooth to the inner surface of the tooth, is angled relative to the longitudinal center plane of the blade body. the blade body is formed so that both the longitudinal axis and the lateral axis of the blade body are curved so that the teeth are arranged in a first curve that extends proximally to distally and a second curve that extends between the opposed sides of the blade body; and said teeth are formed so that on each side of the longitudinal center plane of the blade body there is at least one tooth (190b-190i) that has a rake surface that is located on an axis that, extending from the outer surface of the tooth to the inner surface of the tooth, is angled relative to the longitudinal center plane of the blade body.
