Amalgam Two Or More Weapons

As some of you may have read, I am creating my own comic series for fun and what some of you may not have heard of is one of my heroes named Der Anzung, anyway, this character is super rich and has tons of weapons in his inventory that he has customized. What I want you to do is to find two real weapons and tell me what their combined mechanics could do. My favorite response will be labeled as best answer. This forum is for the artists who would like to draw out their idea.

@shatterstar can you please pin this topic

Maybe you can get a Takomak torus generator (something like iron mans chest reactor) as a ring on his finger without all the defenses and vacuum tunnels, then he can throw it out and it grows, anything caught within it's wall of hydrothermalnuclear liquid gets vaporized. i'll think of something better when I come back from school. You said it has the be real weapons, so I just thought of the most expensive thing lol.

@deadcool_xd: Do you mean real world weapons?

a knife-sword = a knife that extends into a sword

yeah
