Have you ever resorted to heating the butter with a hair dryer to avoid tearing your bread?   Warburton’s Toastie Knife blade warms up to 107.2 Fahrenheit, giving it the optimal temperature to cut through the butter without immediately melting the substance. The knife is powered by two AA batteries and has a short blade surface with a large, bright orange grip to stand out from your average cutlery. This should also be easy to point out to the kids to be extra careful about, since touching the hot blade during power might be a shock to an otherwise cool feel of the average steel cookware.

Nancy Note:  This sounds like a very useful item, but unfortunately is not available on the market.  If it does become available, you will be the first to know.
