I know I hate that part too. Try to slide a long pin or a box cutter carefully between the blades.

Most of our blades come in single packs and I think they are made from gold as the latest price in my area is $16.95 so there is no danger of me going anywhere near them!lol
(In all seriousness, I am using the blades I received as a gift from another member - and gratefully too,) The way I prize stuff like that apart is t use a stiletto.
