Quickest one I remember was actually a Craftsman Torx screwdriver set, and this was maybe 10-15 years ago when they were still USA made. Unboxed 'em and went to work doing a tuneup/carb adjustment on an old Studebaker with a Carter AFB carb. Second or third screw to loosen the choke housing, and this was not an old ****** carb, just one with the screws normally snug, the damn handle twisted on the shaft on me.
Fortunately this was back in the day when they still had open stock, so back to Sears I went and got a replacement which I still have. However, it did shake my faith in Craftsman a little as up to that point I'd had excellent service from every Craftsman tool I'd touched.
Next would probably be my 10/11mm Craftsman flare wrench... made of pressed cheese, although to be fair, it did get abused on every job. But shouldn't that be expected with a flare wrench? (they're all SK or Snap-On now...)
