I was excited to find these at Bed Bath and Beyond.
It's a set of four and they are each marked for their appropriate use! There is a vegetable, seafood, poultry and meat version. I've become a little paranoid about kitchen things since my bout with food poisoning and since others in the house aren't as paranoid as I am, I always wonder if they are paying attention. Now they can see exactly which one to use!
