According to the laws of phisics, it is not possible to make a light bladed melee weapon. However there is an alternative. Using a noble gas like
helium for a base plasma in a dynamic, expanding state, the effect would be the same. Having a specially metered amount of the plasma and running a
brief electric current through itWould give you the "extending blade". to make the blade retract, you would have to rob the initial charge away.
You would actually only require the power from a 9 volt battery to give it the initial charge. the only problem that you would run into during the
construction is containing the collapsed plasma. The heat would melt anything that you could contain it in. Given some new alloy or element yet
undiscovered, it would be possible to create a plasma bladed sword that functioned exactly like the light sabers in the movies.

matter.
