Thor is Odin's son and Odin is the chief of the Norse gods, so in that sense he has some influence over Thor, but Thor is generally depicted as vengeful and hot-headed. As such, if he was bashing some poor giant's head in, it is probably of his own volition, not because Odin commanded it.

Also, Thor's hammer was crafted by dwarves when Loki made a bet that they could not craft treasures more precious than Odin's spear, Sif's golden hair, and Freyr's boat. Odin didn't really have anything to do with it directly, though he did end up getting a pretty sweet ring from the deal.
