Hi Guys,
I am with colin; keep the cutlery in the house! However, I would also shred the old credit cards!
Badge removal is about the only use for all those plastic "loyalty" cards the supermarkets give out; same advantages as the credit card idea, but they are disposable.
For removing big mouldings (or things like number plates with sticky fixers!) which are on with the foam tape, try a length of thin wire- Stuff like Cheesewire is what you need- and work it along the moulding. Watch out for hidden clips, but they should come off lovely!
In all cases, a bit of heat will help.
