A broadhead arrowhead of the type having replaceable blades is formed with a central body which has slots which receive the replaceable blades and plural sets of holes formed radially therethrough to give the arrowhead significantly reduced weight compared to arrowheads of similar size, while retaining high strength and rigidity. Each set of holes is formed as a line of holes extending lengthwise along the central body, with the size of the holes from the back to the front of the body preferably decreasing in size to match the taper of the cross-sectional diameter of the central body. Where three blades are provided, six sets of holes may be formed in the central body by drilling through the central body, with the slots for admitting the blades extending through three of the sets of holes. In addition to reducing weight, the holes also provide a wind foil which is effective to reduce the noise of the arrow in flight and to improve its stability.
