## Abstract

A composite bat is formed of a stiff core having a thick sheath of an elastomer such as a polyurethane. The bat can have an oval-shaped handle covered with a high friction grip. The elastomer sheath is resistant to water and oil. The bat is useful to hit and stun or kill fish without rebound. The core can be formed of a pultruded resin-fiberglass composite having good adhesion to the elastomer sheath. The bat can also take the form of a billy club.

## Claims

### Claim 1

A composite bat comprising in combination: a stiff core rod of ovoid cross section, said core rod extending 90 to 95 percent of the end to end length of the bat and having a first portion supporting a handle and a second portion supporting a striking section, said first handle portion forming 20 to 40 percent of the length of the bat, said handle comprising a separable plastic cover of oval shape tightly embracing said ovoid core rod forming a hand grip of oval shape, said striking section comprising a cylindrical elastomer sleeve encasing and bonded to said ovoid core rod.

### Claim 2 (depends on 1)

The combination of claim 1 wherein said cylindrical elastomer sleeve includes an integrally molded rounded end cap covering said core rod at an end portion of said bat remote from said handle.

### Claim 3 (depends on 2)

The combination of claim 2 wherein said cylindrical elastomer sleeve includes a cylindrical tapered section extending in the direction of the handle.

### Claim 4 (depends on 3)

The combination of claim 3 wherein said core rod is formed of a composite resin having parallel reinforcement fibers embedded therein.
