Seam ripper

A cutting tool comprising a holder and a blade, the forward edge of said holder having at least one V-shaped notch for exposing a portion of the cutting edge of said blade, said blade edge extending across said notch perpendicular to a line bisecting its vertex and deeply recessed within said notch, said holder having a guide portion with upper and lower substantially planar surfaces obliquely disposed with respect to the plane of said blade, wherein the planes of said surfaces converge in a line disposed transversely forwardly of the blade so that said surfaces form a wedge to separate materials sewn together by a seam prior to engagement of said seam by said blade when said tool is moved along said seam with said blade oriented substantially perpendicular thereto, wherein said V-shaped notch includes a pair of inner walls whose planes intersect with the planes of said upper and lower holder surfaces, further including a plurality of beveled surfaces extending along a portion of the juncture between said upper and lower surfaces and said inner walls adjacent the vertex of said notch.
