Electro-sword
From MediaWiki
Like the rest of his sword-wielding Predacon teammates, Tantrum also carries a sword. In his case, it's an electro-sword, which is perpetually sheathed in a web of powerful electric bolts that can disable his prey in addition to being sharp and pointy. Owie.
Insecticon overkill extraordinaire Barrage also packs an electro-sword, of his own. He mostly just uses it to hack your body into itty-bitty pieces after he’s shot you in the face five times.
Blitzwing has an electron scimitar, a weapon that's been in use since ancient Cybertronian times. The neomaximal CatSCAN is also equipped with a pair of these weapons.
Finally, Splashdown favors an electron sword as well.
