Butter Up Knife

I just received my Butter Up knife in the mail today. I found this knife on Kick Starter and pledged. It works really well.

The Butter Up knife quickly turns cold, hard butter into sumptuous easy to spread ribbons.

One side of the knife has a built in grater to aerate and soften butter making it easy to spread, the other side has a serrated edge for cutting bread. A wider blade helps to collect the grated butter as well as provide more surface area for easy spreading.
