In my Aracana Evolved game, an unfettered (swashbuckler fighter type). This character was made after a near-TPK, so has several levels and history to start with.
First session, the player, who had been working out of the old Arcana Unearthed book, asked about parrying weapons. He hadn't found any in AU or the PHB, and the closest he could find was the jitte from Oriental Adventures, a disarming weapon. I pointed out that AE included the main-gauche, which would give him a parry bonus, and was a better weapon than the jitte (1d4, 19-20 x2 vs 1d4 20 x2). The game hadn't started, so he picked one up.
Note, he picked one up. He didn't switch out the jitte for a main-gauche; he kept it as his primary weapon. A ghost-touched jitte, used as his on-hand weapon, with a rapier as his off-hand weapon. His explanation for the jitte was that he was from a seafaring family, and the jitte was their traditional weapon.
This same character later refused to leave his horse behind when the party was in a hurry to cross an unstable bridge. His reason: the character had owned the horse for 10 years, and was quite bonded with it. I'll repeat: the character, with a seafaring background, had owned the horse for 10 years. The logical dissonance ended when another character accidentally Sorcerous Blasted the horse out of existance.
