Small Diameter Double Cutter Crossbow Bolt
First Claim
1. A small diameter double cutter crossbow bolt comprising:
- an elongated shaft formed with a lumen and having a central axis, a front end, a tail end, and an outer surface having a first diameter;
a spacer, formed as a collar having an outer diameter and a cylindrical axial bore with an inner diameter greater than said first diameter of said elongated shaft, and slidable along said outer surface of said elongated shaft, wherein said spacer further comprises a leading aerodynamic surface and a trailing aerodynamic surface; and
a plurality of blades extending axially from said spacer.

Abstract
The small diameter double cutter crossbow bolt of the present invention incorporates a midsection spacer having a plurality of blades, positioned mid-shaft of a small diameter shaft having a nock and a tip. The nock and midsection spacer has an outer diameter equal to the outer diameter of a standard bolt to ensure the centerline axis of the bolt is the same as a traditional crossbow bolt, allowing the use of the small diameter double cutter crossbow bolt in standard crossbow stocks and rails. In a preferred embodiment, midsection blade is formed with a lumen and is slid over the small diameter shaft. In an alternative preferred embodiment, the midsection spacer is a solid unit, joining two halves of a small diameter shaft. Thus, the small diameter double cutter crossbow bolt of the present invention provides a crossbow bolt capable of greater speeds, range, accuracy, kinetic energy, and lethality.
