Abstract
An axially compact broadhead for archery and other such purposes is disclosed. The broadhead may be formed from a tip configured to facilitate penetration of the tip into an object with a pointed distal end and an opposite proximal end. The tip may include a central tip chamber extending distally into the tip from the proximal end and a plurality of blade slots extending from the proximal end of the tip toward the distal end. A base may be positioned proximally of the tip and have a central base chamber. One or more blades may be positioned in the blade slots and extend outwardly from the tip. An elongated engaging bar may extend through the central base chamber of the base and into the central tip chamber to affix the blades and provide a post for attaching the broadhead to an insert of an arrow.

A broadhead, comprising:
- a tip configured to facilitate penetration of the blade into an object with a pointed distal end and an opposite, open proximal end;
- wherein the tip includes a central tip chamber extending distally into the tip from the proximal end and at least one blade slot between an outer surface of the tip and the central tip chamber and extending from the proximal end of the tip toward the distal end;
- a base positioned proximally of the tip and having a central base chamber;
- at least one blade positioned in one of the at least one blade slot and extending outwardly from the tip, wherein a securing flange extending from the at least one blade extends into the central chamber;
- and
- an elongated engaging bar having a threaded proximal end and a threaded distal end and extending through the central base chamber of the base and into the central tip chamber, wherein the threaded distal end threadably engages the threaded distal tip chamber.

A broadhead, comprising:
- a tip configured to facilitate penetration of the broadhead into an object with a pointed distal end and an opposite, open proximal end;
- wherein the tip includes a central tip chamber extending distally into the tip from the proximal end, a threaded distal tip chamber extending distally from a distal end of the central chamber, and a plurality of blade slots between an outer surface of the tip and the central chamber and extending from the proximal end of the tip toward the distal end;
- a base positioned proximally of the tip and having a central base chamber;
- a plurality of blades positioned in the blade slots and extending outwardly from the tip, wherein securing flanges extending from the blades extend into the central chamber;
- an elongated engaging bar having a threaded proximal end and a threaded distal end and extending through the central base chamber of the base and into the central tip chamber, wherein the threaded distal end threadably engages the threaded distal tip chamber;
- wherein the elongated engaging bar includes a bar stop extending radially a distance sufficient to contact a proximal end the base;
- wherein the base includes base blade slots corresponding to the plurality of blade slots in the tip that receive the blades and prevent the blades from moving axially rearward;
- and
- wherein the pointed tip is formed from a trocar having a plurality of cutting arrises, wherein the cutting arrises are aligned with the blade slots.
