Abstract

Arrowheads each having a cutting tip defined with a tip body having at least one slot for engageable mounting of a cutting tip blade therein. The tip blades provide a razor sharp cutting edge situated near a forward leading end of the corresponding arrowheads. The tip blade are secured to corresponding tips by holding elements. Some such cutting tips have facets formed thereon. Some such arrowheads are blade-opening arrowheads, whereas other such arrowheads have substantially removably attachable fixed blades disposed therewith, in elongately configured slots upon corresponding arrowhead bodies. The razor sharp cutting edges of the tip blades in conjunction with the corresponding tip bodies and/or facets provide cutting tips of structural integrity so as to sufficiently crush/split heavy bone and push penetrated material easily from its cutting path, while concomitantly slicing soft tissue with the ease of a razors edge.
