1. An apparatus for slicing a cartilage sample, the apparatus having a longitudinal axis extending in forward and rearward directions, the apparatus comprising:
a rear cartilage support cup;
a cartilage clamp positioned forward of the rear cartilage support cup,
the cartilage clamp having first and second clamp members, the first clamp member being spaced apart from and aligned with the second clamp member in a clamping direction transverse to the longitudinal axis, and at least one of the first and second clamp members being movable parallel to the clamping direction;
a front cartilage support, the front cartilage support positioned forward of the cartilage clamp;
a cartilage receiving region bounded by the first and second clamp members, the front cartilage support, and the rear cartilage support cup; and
a cartilage cutting element positioned forward of the cartilage clamp, the cartilage cutting element spaced rearwardly from the front cartilage support by a cartilage slice thickness, the cartilage cutting element being movable across the cartilage receiving region in a cutting direction transverse to the longitudinal axis.
