Abstract
An arrowhead having a combination of fixed and expandable blades is provided. The new arrowhead has three mechanically expandable blades and six fixed blades. An expandable blade is snug fitted in between two fixed blades, eliminating the need for a mechanism to hold the expandable blade during the flight. In one embodiment of the present arrowhead, the expandable blades pivotally open from the front end of the arrowhead. And in the second embodiment of the present arrowhead, the expandable blades pivotally open from the rear end of the arrowhead.
Claims13
A broadhead arrowhead comprising:
- a. an elongated main body with substantially triangular cross section having a proximal and a distal end, said main body having three faces, each said face having three longitudinal grooves, each said groove sized to receive a blade, said main body having three pin-receiving apertures towards its distal end;
- b. nine blades mounted on said grooves, wherein each said face having three blades, comprising of two side blades and one middle blade, wherein said side blades being fixed blades, and said middle blades being mechanically expandable blades;
- c. said fixed blades being substantially triangular having a base which sits inside a groove, a blade web to cut, and a substantially perpendicular side to support the blade web, said base having a tip and an end, said end having an aperture;
- and
- d. each said expandable blade being slanted L-shaped having a longer length with a first-end and a shorter length with a second-end, said longer length of the L-shaped blade being placed inside said middle groove extending from the proximal to the distal end of the main body, and wherein the shorter length of the L-shaped blade extending outwardly close to the proximal end, said expandable blade having an aperture at its first-end, said L-shaped blade having sharp front edges to cut and penetrate;
- e. means to attach said fixed and expandable blades to said main body;
- and
- f. means to attach said broadhead to an arrow,
- whereby each expandable blade opens when the shorter length of the L-shaped blade impacts a target, forcing it to pivot around the pin.

A twin-blade arrowhead comprising:
- a. an elongated main body having a proximal and a distal end, six longitudinal grooves with three grooves on opposite sides of the main body, each said groove sized to receive a blade, said main body having two pin-receiving apertures towards its distal end;
- b. a pair of three blades comprising of two side blades and one middle blade, wherein said side blades being fixed blades, and said middle blades being mechanically expandable blades;
- c. said fixed blades being substantially triangular having a base which sits inside a groove, a blade web to cut, and a substantially perpendicular side to support the blade web, said base having a tip and an end, said end having an aperture;
- d. each said expandable blade being slanted L-shaped having a longer length with a first-end and a shorter length with a second-end, said longer length of the L-shaped blade being placed inside said middle groove extending from the proximal to the distal end of the main body, and wherein the shorter length of the L-shaped blade extending outwardly close to the proximal end, said expandable blade having an aperture at its first-end, said L-shaped blade having sharp front edges to cut and penetrate;
- e. means to attach said fixed and expandable blades to said main body;
- and
- f. means to attach said broadhead to an arrow,
- whereby each expandable blade opens when the shorter length of the L-shaped blade impacts a target, forcing it to pivot around the pin.

A multi-lever broadhead comprising:
- a. an elongated main body with substantially triangular cross section having a proximal and a distal end, said main body having three faces, each said face having three longitudinal grooves, each said groove sized to receive a blade, said main body having three pin receiving apertures towards its distal end;
- b. each said face having three blades, comprising of two side blades and one middle multi-lever blade, wherein said side blades being fixed blades, and said middle blades being mechanically expandable blades;
- c. said fixed blades being substantially triangular having a base which sits inside a groove, a blade web to cut, and a substantially perpendicular side to support the blade web, said base having a tip and an end, said end having a first aperture to fix the blade on the main body, a second and a third aperture on its sides to receive the middle multi-lever blade;
- d. each said multi-lever blade comprising of an expanding lever and a lifting lever, wherein said levers being pivotally attached to the sides of said fixed blades, whereby the lifting lever being engaged with the fix blades and pivots closer to the tip of the broadhead and having a clockwise rotation after impact with the target, and forcing the expanding lever to rotate counter-clockwise;
- e. means to attach said fixed and expandable blades to said main body;
- and
- f. means to attach said broadhead to an arrow,
- whereby the clockwise rotation of said lifting lever results in a counterclockwise rotation of said expanding lever by pushing down one end of said expanding lever.
