Because it's Medium and he uses Small weapons, it's a one-handed weapon for him instead of a light weapon and he has a -2 penalty on the attack roll because of the size difference; but otherwise it's not particularly different from any other weapon he could wield.
Interesting, okay. I mean, I guess the +5 is easily making up for the deficit, given that the geeks determined his off-hand was a +2 before. Now he's wielding +5/+4 if I'm not mistaken?
