A few years ago, we discussed the battery powered, self-heating Toastie Knife. (Un)Fortunately, the Toastie Knife is no longer available. However, there is a new product on the market, THAT! Serrated Warming Butter Knife and it does not need batteries! It is made using heat conducting technology that utilizes your body heat to carve and spread cold butter. It also has a serrated edge designed to curl and soften cold butter easily.
I can’t understand how this product conducts heat differently from any other stainless-steel knife. And conduct heat from my hands? My hands are always cold! If my hands are warm enough to heat a knife, then the room would be hot enough to melt the butter anyway!
No, I’ll save my $16, use one of the knives I already own and heat the butter by putting it in the microwave for a few seconds or leaving it at room temperature for a few minutes.
Thanks goes to reader Kimberly for bringing this unitasker to our attention.
