This suggestion is about the addition of a weapon called Training Lightsaber or Training Blade to vendors.
The weapon type for this weapon would be Lightsaber, but it would only have the most basic or weaker stats than a regular Lightsaber. Both mechanically and from a character point of view.
The weapon could either use the Lightsaber model (like the training lightsabers used by padawans in the movies that have been calibrated or designed only for training purposes - they are essentially glorified tasers). Or - my preferred option - have more of a vibroblade design that emulates the balance, weight and qualities of an actual lightsaber, using a Shortsword or Tanto model.

This way a padawan, apprentice or any other type of Force user could start levelling up the right weapon skill from the start, without diminishing that epic feeling when you finally obtain an actual lightsaber that glows and hums and stuff.
Right now my Force user is awkwardly fumbling their way through the low levels. Just temporarily using weapon types they (really) suck with and plan to abandon completely the moment they get a lightsaber. Which honestly feels a bit redundant. I do understand why you would not want to give players a lightsaber right away, so hopefully this suggestion can provide a good alternative/compromise.
