design details for a butter knife warmer

Hi everyone!
I need help on how to build a butter knife that gets warm. I know I need to put a nichrome wire in the blade but would anything go at the end? Would I connect the wire to a battery? How do I find out what size battery to use and make it so the blade gets to a specific heat?

Any help would be greatly appreciated.

~Thanks

batteries wont last long
nichrome wire might not work at low voltage,there
are other resistance/heating wires available for low voltage applications
