Dalinar's left hand

[Argel]

Not sure if this could mean anything or not, but the only time "left hand" is used to describe a male in TWoK is a figure of speech describing Gavilar and then the rest are all for Dalinar. And there are not any "right hand" references describing Dalinar. Maybe that's because the right hand is just assumed(?).
 

Dalinar raced under the limb, transferring Oathbringer to his left hand and holding the sword out to the side, slashing it through one of the chasmfiend’s trunklike legs. The Way of Kings (p. 204). Kindle Edition.

 

The stuffy, dimly lit barrack was gone. Instead, he stood in darkness. The air was thick with the scent of dried grain, and when he reached out with his left hand, he felt a wooden wall. He was in a barn of some sort. The Way of Kings (p. 295). Kindle Edition.

 

Dalinar waved with his left hand as the armor bearers locked the gauntlet onto his right. He made a fist, tiny plates curving perfectly. The Way of Kings (p. 372). Kindle Edition.

 

Dalinar found himself walking away, helm held in his left hand. The Way of Kings (p. 382). Kindle Edition.

 

He flexed his left hand as he rode; it was now encased by a blue-painted Shardplate gauntlet borrowed from Adolin. The Way of Kings (p. 949). Kindle Edition.

 

Could Dalinar be left handed, or ambidextrous?

Could Dalinar be left handed, or ambidextrous?

Since he's a soldier, moreover the Blackthorn himself, the surprise would be him not being ambidextrous...

[Argel]

True, but no one else gets that treatment, not even Kaladin (at least no in TWoK).

[soulcastJam]

I'm going to go with it just being assumed that he uses his right on unspecified occasions.

[Argel]

It's interesting that no other male is referenced as specifically using his left hand in TWoK. Were these scenes dropped in directly from the original TWoK? Or is there a hint about something here, such as Dalinar being left-handed?

Personally I think he is ambidextrous. My implication from the first scene referenced, is that he is switching to his left hand which implies to me he usually uses his right. The other instance where he waves with his left, is because they first placed the gauntlet on his right, so it was the only hand he had available at that time. I am under the impression you usually rest a helmet under your left or non dominant hand, leaving your right or dominant hand free to take any actions such as drawing your sword or shaking hands. The scene in the barn, he first uses the sword and dagger stance with a poker in one hand and a piece of wood in the other, but I haven't delved deep enough yet to know which was held by which. Same thing regarding using Adolin's gauntlet. My assumption is he used his off hand or left hand to block a blow which is why it got shattered, but again I need to look deeper. I will say it is definitely a great pick up on your part, so upvote. I think personally believe Dalinar is ambidextrous, and given the two hander stances preferred by nobility, probably so are most men in combat. So even if he isn't left handed, we definitely did learn something new

Ah looks like I have opened a box of Pandora by realizing Shshshsh was left-handed... And here I was thinking Renarin perhaps was a lefty in an attempt to explain his very poor combat skills and his inability to improve them at a decent pace but turns out Adolin is the odd one out for being right-handed 

 

Shocking 

[Pathfinder]

So the scene with the gauntlet, he blocked the enemy shardblade with his left forearm to enable him to swing his blade with his right to cleave the stone beneath him. By shattering the forearm, it made the gauntlet unpowered and felt like a lead weight, so later in the combat he slammed his left fist down to remove the gauntlet and fight with his left hand exposed and his right one covered. 

 

Regarding the scene in the barn, although it never states which hand he uses or which side of the body he gets wounded, dear god Dalinar can take a beating. Slashed face with cut on the cheek, raked side, raked arm, and a deep bite to his shoulder. Although that happens all in a vision, but still.
