Does the SpreadTHAT! heated butter knife actually work?

Yes. SpreadTHAT! uses a superconducting metal core inside the blade to transfer heat from your palm to the knife edge in seconds. The warmth is enough to glide through cold, hard butter straight from the fridge without tearing bread or toast. No batteries, no electricity — just the natural warmth of your hand.

Do I need to heat the SpreadTHAT! before using it?

No heating required. Simply hold the handle in your hand for 5–10 seconds before spreading. Your body heat conducts through the superconducting core and warms the blade automatically. The knife works every time — no warm water, no microwave, no waiting.

What type of butter works best with SpreadTHAT!?

SpreadTHAT! works best with cold, unsalted or salted butter straight from the fridge. It also works on coconut oil, cream cheese, peanut butter, Nutella, and other hard or thick spreads. The serrated edge shaves thin curls of cold butter; the flat edge smooths them into an even layer.
