Abstract
The arrowhead assembly has a ferrule having a tip end and an arrow end. The arrow end is structured and arranged to couple to an arrow shaft. The ferrule has plural slots or grooves extending longitudinally. The grooves receive blades. Each blade has a front portion and a rear portion. The front portion is received into a nook on the ferrule, while the rear portion forms a corner that is received by a collar on the ferrule. Some of the blades have first and second cutting edges, wherein the second cutting edge is inserted into the groove while the first cutting edge is exposed for cutting. The blades are reversible in that the first cutting edge can be put into the groove while the second cutting edge is exposed. The grooves have an edge keeper to prevent the cutting edge from becoming dulled through contact through the ferrule. There are also disclosed lopper type blades which have cutting edges swept forward.
