Bone implants and cutting apparatuses and methods

A method of assembling a hard tissue reamer assembly, comprising:

• obtaining a reamer, the reamer comprising:
• a shaft with a first end and a second end;
• a cutting member coupled to the second end of the shaft;
• and
• a groove in the shaft near the second end of the shaft;
• obtaining a reamer sleeve, the reamer sleeve comprising:
• a base portion having a top surface and a bottom surface;
• and
• a securement mechanism extending away from the top surface of the base portion, the securement mechanism comprising:
• an opening extending through the securement mechanism to the bottom surface of the base portion;
• at least one engagement member adjacent the opening;
• and
• at least one engagement protrusion extending from the engagement member into the opening;
• aligning the opening of the securement mechanism of the reamer sleeve with the shaft of the reamer;
• sliding the reamer sleeve down the shaft of the reamer toward the second end;
• and
• engaging the at least one engagement protrusion of the securement mechanism in the groove of the shaft of the reamer.
