Have not used it in years. I also have an electric knife and we never use it either. We just forget about them.
I don’t think my mother had a fondue set or a electric knife, but we had a crepe pan, the kind with almost a dome. I don’t remember her making crepes after the very early 80s.
The electric knife is great for cutting packing foam. I everytime I find one at a thrift store I pick it up.
I have never cut anything else with one....
