Threaded Power Baton

Kind of a two-edged sword...

I noticed a while back that the threads on woodscrews can be pretty wicked. They're razor sharp, and provide a lot of cutting surface if used a certain way.

This is a baton about the same diameter as a D-Cell powered Mag-Lite. It is approximately 18-24 inches long, depending on your preferences. It's the same diameter along its whole length, and threaded along its whole length, except for the handle, which is a separate piece. Intended more as a weapon of intimidation than anything else, it is designed to instill fear in its victims. Not only are the threads razor sharp, it is inserted in and removed from its tubular scabbard much like a power screwdriver. The handle is filled with batteries and has a two-position thumb switch. To sheath or draw the weapon, it is operated exactly like a power screwdriver. Hold the handle firmly, press the button, and the baton threads in or out, making a terrifying whirring noise. The lubricated scabbard is designed so that it sharpens the threads with every removal.

For use in combat, there a variety of uses. You can swing it unpowered, or thrust it with the power on if you have the tapered version. Brutal and effective as a weapon, you may want to make sure you have some cover fire while drawing this weapon, as it may take a while (Hence the subtitle). And pray it doesn't become cross-threaded in the scabbard.

The Geneva Conventions http://en.wikipedia...i/Geneva_Convention
Four treaties and three additional protocols [8th of 7, Jan 06 2010]

       Will it make an interesting "BZZSSSSSSSSHHHHHH..... WHUM ...... WHUM ......." noise ?

       And thus although only a boy, Robert's son Phillip twisted Helixcalibur from the stone to be dubbed from that day forth as...Aurthur!   

       Auger?

       Wow, this would be a particularly brutal weapon. (+)
  

       Ahhh, to invent something that may have to be mentioned in the Geneva Convention amendment. (+)

       Actually, there is more than one Geneva Convention.

       Wouldn't the spinning cause a gyroscopic effect, making it difficult to wield?
  

       An undeniably odd weapon, though.
Aristotle, Jan 06 2010
  

       It would undoubtedly take some skill and a lot of getting used to, but with the reverse switch it can be made to spin either way.

       Made by Makita? Sounds like something the motorcycle cops in Iran would use.
normzone, Jan 06 2010
  

       Better yet - make it telescopic so that, when the button is pressed, the short flashlight-sized device unscrews itself and extends.

       Ooooooh, YES !

       //Made by Makita? //
  

       Actually, I was thinking Craftsman or DeWalt. But Makita works, too. And Max, the telescoping bit could work very well with a simple ballscrew assembly. The problem you'd run into there, however, is where exactly it retracts to. The handle is full of batteries, remember.

What, you mean you haven't invented annular batteries yet?

       Actually, it should be "cells", which are the individual elements. A battery is two or more cells in an enclosure.

       // I was thinking Craftsman or DeWalt. But Makita works, too// Craftsman is usually black, Dewalt is yellow and Makita is blue. I think yellow is better, but black is interesting. Depends on the effect you are looking for. Yellow is best for deterrent.
  

       Also could I get mine as a tonfa, as I think that would handle the torque better. I'm a little worried that I'd try to drill someone and twist my wrist. Also the arrangement could put the on off switch at the easy of find position at the end of the short handle.
MisterQED, Jan 07 2010
  

       well If you screw someone you either have to let go of the scewsaber or you have to immediately unscrew them otherwise you have to share the same immediate space with a wounded adversary who is still functional enough to wail on you. Terrifying? Yes. Lethal? Yes. Defensive? No. It would be even more uber if it had a "head" on it that caused ripping after the auguring was complete.

       //where exactly it retracts to. The handle is full of batteries,//
  

       Imagine a conventional flashlight (but without the bulb). Now put a slightly larger cylinder around it, threaded on the outside. Now take a yet larger cylinder, threaded on both the inside and outside, and screw it onto the first one. Then a larger one yet, and screw it onto the second, etc. So you have a series of concentric cylinders, similar to a telescope but threaded, with the batteries in the middle.
  

       Now imagine there's a stop on each thread, so each cylinder can "unscrew", but can't completely unscrew from the one inside it. If you now rotate the outermost cylinder relative to the innermost one, the whole assembly will unscrew and extend.
  

       How to achieve the necessary rotation? OK, first, put a "cap" on the front end of the outermost (largest) cylinder. Now take a retractable car arial, but with a square section (so the sections of the arial can't rotate relative to one another). Weld the top of that arial to the inside centre of the "cap". Put a motor in front of the batteries, and connect its shaft to the base of the "arial". Now, when the motor turns, it will turn the "cap", thereby turning the outermost cylinder, thereby extending the device.
  

       There is a snag with this, but it is easily corrected and I will leave it as an excercise for the reader.
