You could get all fancy with this, working out a similar scheme for melee weapon Reach (polearms get +3, spears and greatswords get +2, most one-handed weapons get +1, and little daggers get 0).

That also works for the movie Crocadile Dundee where the muggers have a small knife and he pulls out his and says "You call that a knife? This is a Knife!"
