[Star Wars] Is Luke Skywalker left-handed?

He wields his lightsaber mainly right-handed but he seems to do most things with his left. When he loses his right hand, he seems to be very skilled in using his remaining hand. I know Hamill himself is left-handed.

In the books masters couldn't tell which was his dominate hand while practice dueling him. He took on 3 masters to keep his skills up. If pressed I'd say neither some people are very ambidextrous. Even after his hand got hacked off he worked really hard to get used to it and had its sensitivity up graded a few times.
