I don't like them but here is the full thread discussing these two spells:

The reason I don't like them is that only one thing can be controlling a weapon or object: two forces will put them in contradiction not in conjunction. Either your mind through your magic is moving it or the muscles are moving it. The hand try to move it one way, the magic another. You are not to get best of both, you are more likely to get one sabotaging and working AGAINST the other for lowering score in net effect.
Being as my inclination is to make magic superior in this case, I would rule this is good way to use finesse instead of weapon skill for fighting. A huge advantage actually since you only need one finesse skill instead of multiple weapon skills (brawl, single weapon, great weapon, bows, etc).
