gbuskirk beat me to the list. Virtually everything in your house would now qualify for Prop 65 notice requirement. It's pretty ridiculous now, the original intent of the listing (which was questionable at best) has been diluted so much by the extensive list that it is essentially meaningless for the average person. Yet every business has to keep up with that list, and post signs that warn people if anything on the list is found on the premises.
And if you knew how they arrive at the "known to the state of Kommiefornia to cause cancer" you would just scoff at it. Many cancer studies involve feeding rats huge quantities of a chemical to see if they develop tumors. The studies do not take the time to determine carcinogenicity caused by long term low level exposure. For example, some artificial sweeteners are on the list, but to consume the same dose that raised cancer probability in the test rats would require you to drink many, many cases of artificially sweetened drinks every day.
My guess is that the adhesive for the scales used a solvent that is on the list. Of course, the solvent is long gone once the adhesive is cured, but that doesn't matter to the politicians in this state.
Or, for the fixed blades, it could be the phenol used for the phenolic resin handles. Again, very little left after the polymerization, but why let facts get in the way of scaring people for political gain?
If they were to strictly enforce the Prop 65 law, all of the municipal drinking water in this valley would have to be listed because of the radionuclides that are naturally present (mostly Sierra-derived uranium).
