Grindcutter

I am not sure how many people will recognize this, but the Grindcutter is actually a device shown in the manga Battle Angel Alita.  In the first volume of that manga, Alita fights a cyborg who is able to shoot tentacles out from his hand at supersonic speeds.  That weapon is called a Grindcutter.

And this is the same type of weaponry that GERL uses to rip her own cybernetic enemies to shreds.  So that's a fun little thing that only people who read this blog will likely be aware of.
