摘要： Arrowhead cutting blades having a sharper cutting edge, wherein the angle between opposing grind bevels on either side of a corresponding cutting edge is narrower than that which an arrowhead cutting blade of the same thickness would of normally had. Such an arrowhead blade cutting edge is ground on a necked down thinner edge portion of the precursor blade article (blade form or blade shape) during a strip grinding process (but not limited thereto), wherein the blade has a pair of opposing side faces, an inside corner and a step disposed between each side face and the cutting edge, so as to define the narrower cutting edge angle thereof.
摘要翻译：具有更锋利的切割刃的箭头切割刀片，其中在相应切削刃的任一侧的相对研磨斜面之间的角度比通常具有相同厚度的箭头切割刀片的角度窄。在条带研磨过程（但不限于此）期间，将这种箭头刀片切割刃在前体刀片制品的颈缩较薄边缘部分（刀片形式或刀片形状）上研磨，其中刀片具有一对相对的侧面，内角和设置在每个侧面和切割刃之间的台阶，以限定其较窄的切削刃角度。

摘要： A modular broadhead having a blade carrying body, a unitary blade unit with multiple blades each with razor edges extending radially from the front of the unitary blade unit rearwardly to a base, and a locking collar for securing the unitary blade unit to the blade carrying body. The base of each blade extends inwardly toward the central axis of the unitary blade unit and forms a tab capable of being slidably received in a rear slot on the blade carrying body. The blade carrying body has multiple rear slots to receive each tab. The blade carrying body has multiple front slots for slidably receiving each of the blades toward the front of the unitary blade unit. The blade carrying body has outer threads forward of the rear slots. The locking collar has inner threads capable of mating with the outer threads on the blade carrying body.

摘要： Blade-opening arrowheads with removably attachable pivotal blades, each having an edge with at least a section thereof that is sharpened for cutting. The sharp cutting edges are prevented from being dulled from contact with their corresponding arrowhead bodies, arrowhead tips or other structure when the blades are folded into a retracted in-flight position or into a closed position by means that prevent the sharp cutting edge(s) from contacting against a substance.

摘要： A rotatable arrowhead having a blade-carrying body that rotates with respect to a shaft that is attached with respect to an arrow shaft. In one embodiment, the rotatable arrowhead has a body and a tip portion that preferably rotate together with respect to the shaft of the arrowhead. The shaft extends within a through bore of the body. A portion of the shaft has a peripheral retention groove about at least a portion of a periphery of the shaft. The tip portion accommodates a retainer. In an assembled condition of the arrowhead, the retainer is positioned within the retention groove. In another embodiment, the rotatable arrowhead has a body that rotates with respect to the shaft of the arrowhead. The shaft extends within the through bore of the body, either partially or completely. The retainer can be mounted within the body or the tip portion, depending upon whether or not the tip portion rotates with respect to the body.

摘要： Disclosed is a broadhead arrowhead. The broadhead arrowhead includes a ferrule, one end portion of which is tapered to a substantial point. One or more blade assemblies extend outwardly from the ferrule. Each blade assembly has a first substantially planar main surface portion disposed in a plane at least substantially parallel to a longitudinal axis of the ferrule and a second surface portion having a planar region offset at an angle to the plane of the main surface portion. A generally continuously curved region is disposed between and connecting the first and second substantially planar portions, such that the blade assembly has an airfoil-type shape.

摘要： A broadhead includes a ferrule for mounting an arrowshaft, the ferrule having a locking portion. At least two blades are mounted on the ferrule (three are used in the preferred embodiment), the blades being coupled to the ferrule in their center portions by notches that mate with the locking portion of the ferrule. A locking nut is mounted on a rear portion of the ferrule for holding the three blades in place on the ferrule when the locking nut is tightened.

摘要： A unitary blade unit for an archery broadhead includes a tip structure and at least three blades inseparably connected into a single blade unit. The blade unit requires a separate ferrule in order for the blade unit to be secured to an arrow. Thus, the blade unit can be replaced while retaining a previously used ferrule, or vice versa. In a preferred embodiment, the blade unit is formed by metal injection molding.

摘要： A broadhead having a penetrating forward tip, a longitudinally extending body with means on the rear end thereof for attachment to an arrow shaft. The body includes a single longitudinally extending passage or, alternatively, two or more longitudinally extending grooves for receiving blades therein. The blades are provided with a longitudinally extending, weight or mass reducing slot and are held within their respective passage or grooves with a transversely positioned or friction holding member which permits rearward sliding movement resulting in outward expansion of the blades while retaining a portion of the blades within the passage or groove. The front end of the blades extends outwardly of the body to contact the target surface to provide a rearward moving force to the blades upon such contact. The slots of the blades are formed to allow the rearward ends thereof to move outwardly to an expanded cutting position as they move relative to the holding member or, alternatively, the blades are directed outwardly by an additional transverse, camming member as they move relative to the holding member.
