Tazer / Sword - This is awesome ! Can someone tell me what practical use it would have?

FOr those who like to paralyze their victims before chopping them up?

For those who think a strong dose of electricity will be needed after cleaving someones arm from their body?

So you can paralyze an opposing fighter to keep them from stabbing you back while they are hanging out on the end of your sword?

It's a bug zapper ninja sword, for those trecs out into the insect infested swamp while stalking people with a sword.

There needs to be no reason for something like this. Just bathe in its awesome glory!
