Craftsman screwdrivers smell the worst. Some guys I used to work in a shop with said it is the plastic they use. You could try to remove it, but the smell will come back.
2 easy steps to avoid the smell:
1) Don't bring them out in polite company
2) What the H-E-doublehockystick are sniffing tools for anyway! (when I was in skewl kids sniffed only glue)
