The one Force-user we have in our group still doesn't have his lightsaber, but the group itself hasn't made it a point to go after it. We're running The Jewel of Yavin right now, however, and the player is suspicious of the jewel itself, thinking it might be able to be cut down and used as a lightsaber crystal * . Unfortunately, he doesn't have anyone to teach him out to make a lightsaber, and he's only seen one briefly, used by his mentor back on Ryloth. His mentor is no longer accessible, and he only has the most mundane notions of how to construct his saber.
* - He's right, of course. After all, that's what Elaiza wants it for. Of course, the gem is big enough, they could share...
I know I have read this several times. Something went off in my brain this time though. Not that it would be practical or useful, but very very deadly (to the practitioner and anyone else). Most of the lightsabers we see are rounded, but these are just being focused by crystals and lenses. With a really large crystal like this, couldn't you take this and turn it into something like... oh, I don't know... the Sword of Grayskull Lightsaber? Two-Handed Greatsword... don't hang it from your back. Giant crystal in the hilt and a two-hand grip and you might as well add some hilt guards. Yeah... no.... what was I thinking...
