Mind blown...Darth Sinna said:The only thing that gives a saber crystal a purpose is the lightsaber and similar technology, as the plasma field is what the crystal gives its special properties to. Technically you could create a broad-sided plasma field along one side of a sledgehammer and use it that way, but it would only really be useful in "frozen blaster technology". (Lightsaber technology, if you're from post-Hyperspace War era.)

False, some crystals such as solari, pontite and one or two others could be used without the blade due to their connection to the force and have been used in artifacts. See Kaiburr crystal and shards.
Mephite has base properties and is the most common crystal you will likely find with sabers.
