| 摘要 |
An arrowhead for hunting archers includes two or more interchangeable replaceable blades, each of which blades includes two axially spaced outwardly extending knife sections each of which has its leading edges sharpened to increase the depth of penetration of the arrowhead and trailing edges sharpened to facilitate angular penetration and withdrawal. The forward end of the arrowhead is blunt so as to cause it to be deflected away from a bone and to increase the slicing action of the knives. A knife may include dull notches to comb hair into the wound to prevent closure and the blades may be flexible enough to pass easily between adjacent ribs.
