This is a pretty little thing and I love leaving it out with my butter. However, I do not see that it conducts heat any better than any other metal knife, and the serration works about the same as any serrated knife does. Nothing special ... except in the looks department.
We use it like a regular butter knife - but it is more interesting.
Works great, easy to clean, wish the handle was longer. Right-handed only, butter doesn't shred if you're left-handed like me

I really love this product. How often do you forget to take butter out of the refrigerator (in my case, the freezer) and then you have to wait to use it or chance it in the microwave where you may over heat it? This is simple to use, cleans fast, and I consider it a great gift as well as an unusual one, for that cook in your life.
Works really well even on ice cream cake.
