Great idea, I fully support it.
Pointless and a complete waste of time/resources to come up with the various combat animations for each utensil/tool. Not to mention that most of these would break rather quickly and would be present for kicks rather than having any real function.
Games in general are "pointless and a complete waste of time", not serving any real function. What, suddenly killing ogres is serious business, while broom fencing is not? Get a perspective, please.
This will go extremely well with overall feeling of sandbox RPG TES is.
About finishing animations - *everything* is one of these five things, from melee perspective: dagger/knife, sword, club, pole, chain. Or combination of things. Broom? Something in between of club and pole, may use animations for warhammer. Scythe? Two-handed axe. Waste basket? Club. Et cetera.
Sure, it is obviously won't be in Skyrim, because this apporach requires a bit more planning from game design standpoint. Oh, and it includes spears and other polearms as a side-effect.
