Abstract

A broadhead (1) has cutout regions (28) at the rear of cutting blades (14 and 16) to reduce adverse wind effects on the flight of an arrow. The cutting blades (14 and 16) are held in a barbed configuration by frictionally secured rings (20). The cutting blades (14 and 16) pivot to a nonbarbed the rings (20) moving towards tip (2). A threadably connectable arrow shaft protector (8) reduces the costs of manufacturing.

Claims

1. A broadhead, comprising:

a body having a threaded end attachable to an arrow shaft and a pointed end;

a first slot in said body positioned at a first longitudinal location with respect to said threaded end of said body;

a first pair of cutting blades pivotally mounted on a first pivot pin within said first slot in said body, each of said first pair of cutting blades having a fulcrum end and a projecting end wherein said fulcrum end is connected to said pivot pin and said projecting end projects out of said first slot and radially away from said body, said first pair of cutting blades being pivotable from a barbed configuration wherein a rear portion of each of said first pair of cutting blades forms an acute angle with a longitudinal axis of said body extending from said threaded end of said body to a nonbarbed configuration wherein said rear portion of each of said first pair of cutting blades forms an obtuse angle with said longitudinal axis of said body extending from said threaded end of said body; and

a first ring member frictionally secured to an outer perimeter of said body, said first ring member slidable to a position for holding said first pair of cutting blades in said barbed configuration.

2. A broadhead as recited in claim 1 further comprising a shaft protector threadably attachable to said threaded end of said body.

3. A broadhead as recited in claim 1, further comprising:

a second slot in said body positioned at a second longitudinal location with respect to said threaded end of said body;

a second pair of cutting blades pivotally mounted on a second pivot pin within said second slot in said body, each of said second pair of cutting blades having a fulcrum end and a projecting end wherein said fulcrum end is connected to said pivot pin and said projecting end projects out of said second slot and radially away from said body, said second pair of cutting blades being pivotable from a barbed configuration wherein a rear portion of each of said second pair of cutting blades forms an acute angle with a longitudinal axis of said body extending from said threaded end of said body to a nonbarbed configuration wherein said rear portion of each of said second pair of cutting blades forms an obtuse angle with said longitudinal axis of said body extending from said threaded end of said body; and

a second ring member frictionally secured to an outer perimeter of said body, said second ring member slidable to a position for holding said first pair of cutting blades in said barbed configuration.

4. A broadhead as recited in claim 3 further comprising a shaft protector threadably attachable to said threaded end of said body.

5. A broadhead as recited in claim 3 wherein said first and second slots are angularly offset by 90°

with respect to said longitudinal axis of said body.
