Hand-held anti-assault weapon

Abstract

An anti-assault weapon to deter, or defeat, attackers. Weapon includes a body, usually cylindrical in shape, that is open at opposite ends. One end is closed by a closure, while the opposite end is closed by a reversible end cap. Threads are defined on the exterior of the end cap and complementary threads are formed on the interior of the body, so that the end cap is securely joined to the body. In one position, a sharp knife projects axially from the reversible end cap, so that an attacker may be threatened and/or stabbed, if necessary. In a second position, the knife is concealed in the interior of the body, and a stub shaft projects outwardly from the end cap. Serrations are defined on the exposed face of the stub shaft, and the serrations may be raked across the face of arms of an attacker. The serrations inflict pain on the attacker, and simultaneously collect a DNA sample that can be tested to facilitate identifying the attacker.

What is claimed is: 
     
         1 . An anti-assault weapon comprising:
 a) a body made of a rigid material and sized to fit in the hand of a user;   b) a first opening at one end of said body and a second opening at the opposite end of said body;   c) a closure sealing one end of said body;   d) a reversible end cap sealing the other end of said body;   e) a stub shaft projecting axially from said second end cap in a first direction;   f) serrations defined on the exposed face of said stub shaft;   g) said serrations being configured to (1) inflict pain or discomfort on a potential attacker, and (2) simultaneously collect DNA.   
     
     
         2 . The anti-assault weapon of  claim 1 , wherein said reversible end cap can be secured to said body to display either a sharp knife or a serrated surface for collecting DNA, skin tissue; etc. 
     
     
         3 . The anti-assault weapon of  claim 1 , wherein threads are formed on the interior of said body, and cooperating threads are defined on the exterior of said stub shaft of said reversible end cap whereby said reversible end cap is screwed into engagement with said body of said weapon. 
     
     
         4 . The anti-assault weapon of  claim 1 , wherein said reversible end cap is secured to said hollow body by a bayonet connection. 
     
     
         5 . The anti-assault weapon of  claim 1 , wherein a compartment is formed in the interior of said body, said compartment receiving currency for safekeeping. 
     
     
         6 . The anti-assault weapon of  claim 1 , wherein said closure is a screw cap. 
     
     
         7 . The anti-assault weapon of  claim 6 , wherein metal rings are secured to the end of the body adjacent to said screw cap, said rings retaining keys and whistles. 
     
     
         8 . The anti-assault weapon of  claim 1 , wherein said weapon is made of metal and said body is cylindrical in shape. 
     
     
         9 . The anti-assault weapon of  claim 1 , wherein threads are formed on the exterior of said reversible end cap, and internal threads are defined in said body, said reversible end cap being screwed into engagement with said body. 
     
     
         10 . The anti-assault weapon of  claim 1 , wherein said closure comprises an end cap.
