The Butter-Up Knife is designed to make it easier to spread cold butter on toast. This handy knife takes a block of butter and turns it into ribbons that are then much easier to spread across your bread without tearing it. Designed and tested by a group of self-proclaimed "butter enthusiasts", who prototyped a plethora of models before finally settling on a design that features a wide blade with built-in grater for maximum butter-to-bread surface area.
