[SW] Is it ever stated in-universe that you need to be a force sensitive to use a lightsaber?

Because I call bs on everyone on the internet claiming you'll cut your hand off if you're not.

Sure, there are examples of non-force sensitives using a lightsaber ( Pre Viszla, Grievous). 


However they are both world class fighters, so they aren't a good sample. A random person off the street who picks up a lightsaber will invariably cut themselves, simply because the near weightlessness doesn't go well with a super hot beam of plasma.

As well,  a lightsaber is a clunky weapon if you are not force sensitive, so that is why you only see Jedi use them.
