Here is how to gauge your own skill with a weapon in the post:
Hopeful: The non-mentioned rank when you list "Skill level from Padawan to Grandmaster", you are so terrible with it, that you don't even consider using it, and have had dreams where you could at least hit a can from an inch away.
Padawan: Low, nearly nothing. You are so untrained in the use of the weapon that you rarely, if ever, even hit anything.
Initiate: You are not to well trained with it, but you are good enough to get by. This is alot of Denzeins average skill.
Knight: You are well trained, and very good with the weapon, and surpass most people in it when you use it.
Master: You are very well trained in the weapon, exceeding some of the best with it. This is usually what most Jedi and Sith are in every form of Lightsaber Combat.
Grandmaster: You are without equal, nearly unstoppable with the weapon. You are considered a god of the weapon.
