Do you have Craftsman tools or Xcelite tools? Xcelite is not a type
of plastic, it's a brand name. While Xcelite screwdriver handles do
not have any inherent odor, that I recall, some of their containers
definitely did. Casein plastic is often made from organic proteins
and often stinks like sour milk. Xcelite interchangeable
screw/nut/allen driver sets used to come in casein plastic boxes.
Ooo-eee! Definitely stinky.
