Double-ended Lightsaber. Looks awesome, but there's a huge chance that you'll slice off your own limb. Seriously. And the handle isn't nearly long enough to use like a Bo Staff, so your grips are limited.
that's why they use the force.
Seriously, they use their attunement with the force to have a supernatural awareness of where their body is, in relation to the lightsaber. It's explained pretty clearly. A double bladed lightsaber would require a lot more care in its use, but using the Force, it's definitely not the most hard to believe things jedis do.
