Those bars are quite useful at moving and prying objects.  I have some scattered around the house, but I use the same models in excavating fossils.  The field conditions I encounter often find the desired specimen locked in a large conglomerate/gravel deposit, where one is often prying largish rocks out to "unlock" the desired bone.  They work quite well, better than any knife, and can take quite a beating.
I also have some long (five feet or so) hexagonal bars, pointed at one end, with a chisel at the other.  One can shift amazingly heavy items with one or two of those.
