A surgical instrument having a forceps handle, a forceps jaw comprising a stationary jaw and a pivotable jaw, and a steel core connecting said forceps handle with said pivotable jaw for pivoting said pivotable jaw for selectively opening and closing said forceps jaw upon actuation of said forceps handle, the improvement which comprises:

said stationary jaw having a first surface provided with a serrated portion and an indented portion; and

said pivotable jaw having a second surface opposed to said first surface of said stationary jaw provided with a serrated portion that cooperates with the serrated portion of the stationary jaw, and a projecting ridge portion, opposite said indented portion and received therein when said forceps pivotable jaw is closed said projecting ridge portion being provided with a recess surface extending from one side of said projecting ridge portion proximate to said second surface toward a second side of said projecting ridge portion remote from said second surface so as to define a cutter on said remote portion wherein said recess surface defines an opening for introducing a surgical thread into said indented portion of said stationary jaw when said projecting ridge portion is received in said indented portion.

2. A surgical instrument according to claim 1 wherein said recess surface is concave in shape.
