How about this:
An electrical heated kitchen knife to cut just a piece of a frozen p�t�, pie, meatloaf, etc. for the microwave. Especially the ones containing a lot of water and that are just impossible to cut with a regular knife while they're frozen.
Does it already exist?
Since I don't have an intern from NYU and I'm very lazy, I hope someone else will do it for me, so I can buy it soon at the store :-)
