Well since i was revamping some of the old idea's from my previous render sword idea's i decided to make a new gen beam render but unlike the others it has an off/on switch! The bottom image is the Beam Render in activation mode the squiggle just means i was too lazy to draw its full length so i used the squiggle to substitute that length.

Pro's:

Like the mech heat sword it will cut anything in half with little effort
It's light weight and can be one handed
Make a nice humming sound
Can be used to open thick metal doors

Cons:

It can take off an arm, leg, foot, finger, or head if the user is careless
If it is submerged in water it will short out and give the user a nasty if not fatal shock.
Does not come with the force.
