Abstract

A broadhead for an arrow has improved opening characteristics and an adjustable cut span such that an archer may adjust cutting span of the main cutting blades of the broadhead to balance penetration with cut width. That is, cut width may be reduced to increase penetration depending on the type of target the archer or hunter is faced with. The arrow includes a collar threaded on the main body of the broadhead to limit the rearward travel of the main cutting blades as they pivot open from the main body of the broadhead upon impact with a target, such that moving the collar by rotating it about the main body adjusts the angle and cut width of the main cutting blades in their deployed position. The broadhead further includes forward cutting surfaces on the main blades configured to open the blades upon impact with the target.

a blade tip extending outwardly from the forward cutting surface and generally perpendicular to the longitudinal axis of the main body when the blade is in the retracted position.

2. The broadhead of claim 1 , wherein:

the stop position of the adjustable stop sets the angle of the main cutting surface of the blade with respect to the longitudinal axis of the main body when the blade is in the deployed position by limiting rearward travel of the blade as the blade pivots rearward to the deployed position from the retracted position when the broadhead impacts a target.

3. The broadhead of claim 1 , wherein:

the main body forms a tip for penetrating a target at a forward end of the main body;

a blade tip extending outwardly from the forward cutting surface and generally perpendicular to the longitudinal axis of the main body when the blade is in the retracted position; and

in the deployed position, the main cutting surface of the blade has an obtuse angle to the longitudinal axis from the tip of the main body and an acute angle to the longitudinal axis from a rear end of the main body.

9. The broadhead of claim 8 , wherein:

the stop position of the adjustable stop sets the angle of the main cutting surface of the blade with respect to the longitudinal axis of the main body when the blade is in the deployed position by limiting rearward travel of the blade as the blade pivots rearward to the deployed position from the retracted position when the broadhead impacts a target.

10. The broadhead of claim 8 , wherein:

the main body has a threaded portion configured to engage an arrow shaft at a rear end of the main body; and

the slot is between the tip and the threaded portion with respect to the longitudinal axis of the main body.

11. The broadhead of claim 10 , wherein the adjustable stop comprises:

adjustable stop threads integral with the main body of the main body between the pivot point of the blade and the threaded portion of the main body with respect to the longitudinal axis of the main body; and
