We have seen various offshoot designs of the lightsaber... the Bo, as represented by Darth Maul's, the Tonfa as used by Maris Brood and the lightsabre whip utilized by Silri. I haven't followed the Clone Wars cartoon series or read the comic books. Have there been or are there any other lightsaber designs?
I fought on the battlefield. I retired to embrace a life of discovery and profit. I carve my own path in life and am better for it.
