I'm really confused by the multiple suggestions that the OP replace his disgusting acetate handles with a new and equally disgusting set of drivers with acetate handles. rcsec, the foul odor is due to the material from which the handle is made, not the manufacturer or the COO, so keep that in mind when shopping.
I have a bunch of other brands of acetate screwdrivers and my Craftsmans are the only ones that seem to really stink.
It makes sense that different brands could use different acetate formulations.
Right now I have the following acetate screwdrivers:
Wilde
Pratt-read
Xcelite
Irwin
Truecraft
Malco
I just went through and smelled them all, and it seems that they don't stink like the Craftsmans. A couple of them do smell a little. I noticed the Xcelite has a little smell.
The Craftsmans stink, but all the ones I have that are stinky are made by Western Forge. I have one Pratt-Read Craftsman screwdriver. I don't know if that one makes a bad smell. It's in a box with a bunch of stinky WF Craftsmans, so it stinks for sure from being with its stinky relatives.
Plus, the European brands I listed appear to have plastic handles, not acetate handles.
EDIT - I just found some older yellow Protos that seem to have a stink, as well.
