The best heated butter knife in NZ — spread cold butter straight from the fridge
SpreadTHAT! is the award-winning heated butter knife that uses the warmth of your hand to melt butter as you spread. No electricity. No waiting for butter to soften. Just perfectly spreadable butter, straight from the fridge, every time.
How the SpreadTHAT! heated butter knife works
SpreadTHAT! uses a superconducting metal core inside the blade to transfer heat from the palm of your hand to the edge of the knife in seconds. As you hold the handle, your body heat travels down the blade — gently warming it just enough to glide through cold, hard butter without tearing your toast. No batteries, no charging, no cords. Just clever engineering.
What you can spread
- Cold butter straight from the fridge
- Peanut butter and nut spreads
- Chocolate spread and Nutella
- Cream cheese
- Coconut oil and hard spreads
Two ways to use it
Use the serrated edge to shave fine curls of cold butter directly onto your toast. Then flip to the flat edge to smooth it into an even, perfectly melted layer. No clumps, no tearing — just a better slice of toast every time.
Award-winning kitchen design
SpreadTHAT! has won multiple international design awards:
-
iF Product Design Award — one of the world’s most prestigious design honours

It is the kind of kitchen gift that people immediately understand and use every single day.
