Schweresturm and Wirbelsturm, twin heavy plasma casters.

They are made so that heat buildup is shunted to the edges of the large ceramic blade on each and they are all powered by betavoltaic cells using heavy hydrogen.

They are also made so that their user could wield two with one hand each as he could wield one with two hands and there are lethality settings on each one set up to be operated using the thumb.

I'm strong enough to wield both of them in each hand, an average fur will have problems lifting just one let alone firing one.
