I dunno, if the wielder had a set of cortosis-alloy armour (a la Jedi Academy), then maybe. But certainly not in what she's wearing, which I imagine provides less protection than a chainmail bikini.

Alternatively, this could be why the jedi are the best of the best. AFAIK, they have to make their own lightsabres, so if someone decides to make that, then I guess they just demonstrate natural selection quite aptly.
