A lot of hand lotions and soaps with lotion in them have shea butter in their formulas.
I do like shea butter, but really, there are a lot of other good things out there for dry skin and splits. (Unscented at that.) I've taken to using a cream that's actually marketed for use on the feet during the winter - it's called Lamisilk. The packaging looks very "girly," but the cream is unscented. It's the best thing I've ever come across for super-dry, callused skin.
I've also used a couple of hand/skin lotions that have goat's milk as one of the primary ingredients, and those are nice, too.
Overall, I think plain shea butter is a little too greasy to use on my hands, but that's just me...
