1. A method of making a monolithic tissue cutting distal end of a biopsy device, comprising:
providing a hollow tube having a first open end, a second open end and an inner lumen extending between the first and second open ends;
removing material from the first open end of the hollow tube to form at least one articulable beak and at least one tendon;
removing material from between the first open end and the second open end of the hollow tube to form at least a tendon actuating element; and
wherein the removal of material enables a differential motion of the second open end of the hollow tube relative to the tendon actuating element, which differential motion causes the at least one tendon to resiliently actuate the at least one articulable beak and at least partially close off the inner lumen.
