ABSTRACT:
A cutter includes a guide tube having a tube proximal end and a tube distal end with a tube distal edge, a segment of the tube distal edge being beveled to form a tube cutting edge and an opposing segment of which defining a tube distal edge proximal recess relative to the tube cutting edge; a line engaging structure slidable within the guide tube for engaging a segment of line; and a displacement mechanism for displacing the line engaging structure relative to the tube cutting edge together with a segment of line retained by the line engaging structure into sheering contact with the tube cutting edge, the tube distal end proximal recess permitting a segment of line retained within the line engaging structure to move proximally past the tube cutting edge so that the line abuts the tube distal edge only at the tube cutting edge during line cutting.
