Tri-blade broadhead with manually sharpenable trocar tip
DCFirst Claim
1. An arrow broadhead comprising:
- a main body having;
a longitudinal axis;
a three-sided chisel tip, said tip generally having the shape of a three-sided equilateral pyramid, the sides of which, being partially cut away, meet at a common vertex that is coincident with said longitudinal axis and which serves as a forwardmost point of the tip, the intersection of each pair of adjacent sides forming a sharpened edge;
a generally hour-glass-shaped portion continuous with said three-sided chisel tip;
a cylindrical portion continuous with said generally hour-glass-shaped portion;
a rearward-facing shoulder formed at the junction of said cylindrical portion and said generally hour-glass-shaped portion;
three blade installation slots, an anterior portion of each slot having a forward-facing recess, and each blade installation slot being aligned with an associated sharpened edge and positioned such that the anterior portion of the slot is adjacent a rearmost point on the associated sharpened edge, and a posterior portion of the slot is in the cylindrical portion; and
a threaded portion continuous with said cylindrical portion for securing the main body to an arrow shaft;
three laminar blades, each of which is insertable within a blade installation slot, each laminar blade having an anterior tab that fits into a forward-facing recess, a posterior extension that fits into the posterior portion of the blade installation slot, and a honed straight edge, each laminar blade being shaped so that when it is inserted within a blade installation slot, the honed straight edge and the sharpened edge of the chisel tip make a generally straight line; and
an annular blade retention collar which slides over said cylindrical portion and traps the posterior extension of each laminar blade, said annular blade retention collar being secured in place by an attached arrow shaft.

Abstract
A hunting broadhead for an arrow has a main body fabricated from high-strength steel, and three laminar carbon steel blades which install within the main body. The main body has a manually sharpenable trocar chisel point tip with three razor-sharp apices. The main body is equipped with three slots, each of which is continuous with one of the three apices of the trocar tip and includes a forward-facing recess at the front end of each slot. A laminar carbon steel blade is inserted into each slot and locked in place by a tab on the front of the blade, which fits into the forward-facing recess, and a notch which engages an annular retainer ring that slips over a rear portion of the main body. Each blade forms an extension of its associated apex, with each apex and its associated blade forming a generally straight line.

8. An arrow broadhead comprising:
-
a main body having a three-sided trocar tip, said tip having a trio of sharpened straight edges which intersect at a common vertex; three laminar blades mountable on the main body, each laminar blade having a honed edge which is aligned with, continuous with, and forms a generally straight line with one of the sharpened straight edges when the blade is mounted on the main body. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An arrow broadhead comrpising:
-
a main body having a three-sided trocar tip, said tip having a trio of sharpened straight edges, each of which is formed by the intersection of adjacent pairs of planar sides of the trocar tip, said trio of sharpened straight edges intersecting at a common vertex which serves as the forwardmost penetrating point of the broadhead; three laminar blades mountable on the main body, each laminar blade having a honed edge which is aligned with, continuous with, and forms a generally straight line with one of the sharpened straight edges when the blade is mounted on the main body. - View Dependent Claims (16, 17, 18, 19, 20)
