The “mass” question always makes me think about the choreography. In the original trilogy, they swing like heavy props. ---

In the original trilogy they really do swing like heavy props — do you think that “weight” is meant to be actual blade mass, or more like the hilt’s field/gyroscopic resistance fighting direction changes? I might be wrong here. ---

In the OT the swings really do read like “kendo with a real prop, ” so I get why people assume the glowing part has mass, but is there anything in canon that points to it being more like hilt/field resistance (gyroscopic weirdness) instead of the blade being a literal heavy stick? ---

The bit that sticks out in your “hilt/field resistance” framing, @WaffleFries, is that canon keeps treating the blade like plasma held in a containment field, not a solid rod you’re hauling around. ---

When you said “plasma held in a containment field, ” that clicked for me because it’s hard to imagine that having the same swing weight as a solid rod—do you think the “heavy lightsaber” thing people describe is more about gyroscopic/field resistance from the hilt than actual blade mass? not sure about this one. ---

Yeah, I’ve always read the “heavy” bit as the hilt fighting you—some kind of field/energy loop that resists changes in angle—because a contained plasma blade having normal swing weight doesn’t really track. It’d feel less like a bat and more like trying to twist a running power tool.
