Abstract
An arrow hunting broadhead has a main body fabricated from high-strength steel, and multiple laminar carbon steel blades which install within the main body. The main body has a manually sharpenable chisel point tip with multiple razor-sharp apices. The main body is equipped with multiple slots, each of which is continuous with one of the apices of the tip and includes a forward-facing recess at the front end of each slot. A laminar carbon steel blade is inserted into each slot and locked in place by a tab on the front of the blade, which fits into the forward-facing recess, and a notch at the rear of the blade, which engages an annular retainer ring that slips over a rear portion of the main body. Each blade forms an extension of its associated apex, with each apex and its associated blade forming a generally straight line.
