I think splitting blade and blunt to compass two handed (two handed swords, halberds, etc), heavy (longswords, hammers, battleaxe etc), medium (shortsword, possibly makeshift weapons like instead of a warhammer an actual hammer) and light (daggers and whatever else is light) would be a more logical division. A longsword fights completely different compared to a dagger, etc.
Also an actual reason for speechcraft to exist would be awesome.
