Is Wedge right or left handed?
My assumption has been that he’s right-handed. Little clues point to that but don’t prove it conclusively. Early in Truce at Bakura, for example, Wedge stops a bomb from detonating by jamming his hand in between two triggering components. Under time pressure, this is the sort of thing one does with his dominant hand, and it was his right hand he used. But I’m not wedded to this answer. Perhaps someday a writer will answer it definitively.
