1. A biopsy device comprising:
an outer needle hub;
an outer needle coupled at a proximal end to the outer needle hub, the outer needle including:
an outer needle tip at an opposite distal end;
a circumferential cutting edge defined at said tip configured for cutting tissue; and
an inner surface defining a lumen through said outer needle for receiving tissue therein, said inner surface including a countersink formed at said tip, wherein the countersink has a length extending proximally from said cutting edge toward said proximal end of said outer needle of at least 0.080 inches;
an inner needle hub; and
an inner needle coupled at a proximal end to said inner needle hub, the inner needle including an inner needle tip at an opposite distal end, said inner needle coaxially disposed within the outer needle,
wherein said outer needle has a thickness from the proximal end of said countersink to said proximal end of said outer needle of at least 0.003 inches.
