Six blade set includes three replaceable 3.5 drop-point blades for skinning and general purpose cuts, two 5.0" boning/fillet blades to prepare perfect cuts of meat for the table and one gutting blade; to easily slice through hide and open game like a zipper without piercing vital organs. Made from Japanese 420J2 stainless steel, precisely heat-treated, and hand finished surgically-sharp for an edge that makes even the biggest big game harvest feel small.
