Ancedata: the lady who works at the cafe near my mom's house sliced her finger clean off making a sandwich. They managed to reattach it and (I've heard) it's healing nicely.

If you wish to read it that way you are welcome to.

Even if you are being totally serious and this is a problem you have... why not buy cheese in blocks and then slice it for your children?

It's not a problem I have because the supermarket sells sliced cheese. Besides that the problem is not with the cheese in slices per se but with the packaging (see top of the thread) and unsliced cheese is also sold in plastic.
