Random-ass inventions! (Random ass-inventions)

[TDK]

Chainsaw Knuckles.



Bear Spear!



I have ideas like this a lot.


Anyone else?

Imagine, if you would, a ring made out of a permanent magnet, with the poles running along the sides, split down the linear center. Now imagine it being put inside a magnetic cuff of the same, but opposite, so that the inside of the cuff repels the outside of the ring to keep it floating. The ring is one of several appropriate cross-sectional shapes (oval, square, triangular, hell, effing star-shaped. anything but a circle) to keep it from turning and having the chance of it sticking to one side or another of the hole through the cuff.

Now imagine having some sort of tether or chain (preferably something light) and a handle with possibly a spike or blade on it for close encounters and secondary use.

What you end up with is essentially a ring with a possibly sharp outer edge floating without concern for friction from anything but air that can be thrown and retrieved easily and will take a LONG time to stop spinning, plus a stabby thingy on the handle in case it gets knocked to the ground or otherwise made difficult to retrieve. The cuff might also have a handle to allow a bladed ring to be used safely for melee. Obviously, there would be different versions.

The main benefits of this would be the ability to easily keep it spinning and the possibility of trapping another iron-based weapon with it either via shape or magnetism. Also, the ability to throw it and get it back is a plus, if you can compensate for the cuff and tether, or if a blade isn't a concern roll it across the ground. If you REALLY want to get high tech, you can fit it with a motor in the cuff to start/keep it spinning and choose between a perpendicular or parallel handle for your very own spinning ring sword/katar.

Rocket propelled chainsaw anyone?

Why exactly is the thread title repeated in parentheses?

[Premmy]

to indicate that the thread is about both inventions that are random-ass and inventions that were randomly created by an ass.

I think it came from this comic here:

Oh, look at that, the hyphen did move. How unobservant of me. Carry on.

Chainsaw arrow. (Bolt, technically)

Only a little bigger than normal bolts, too.

The front of the arrow is mini-chainsaw, and the back is the (tiny) powerbox with stabilizer fins and a accelerometer. The box starts powering the chainsaw when the meter reads a certain speed.

Specially make a crossbow to accomadate it.

Look like a badass.

Exactly how useful is an airborne chainsaw anyway? I mean the collision would hurt like hell, but I don't see it doing any more damage than an ordinary blade being propelled in the same way, seeing as it wouldn't exactly have the time to saw through much without anything to hold it in place.

The title was a reference to the XKCD comic, yes.

Well a similar problem applies to the Bear Spear, but like the Bear Spear it has a secondary purpose, ie intimidation, and also secondary use as a melee weapon/cutting tool.
