While many butter knives can cut into a stick of butter, few (if any) are effective at spreading that same butter onto bread, but that's where the SpreadTHAT butter knife comes in.
SpreadTHAT is an unassuming hot butter knife that easily cuts and spreads cold butter. What sets SpreadTHAT apart from the competition is that it doesn't use any batteries, electricity or hot water to heat up. Instead, the titanium coating of the SpreadTHAT knife houses a copper alloy tube that draws heat from your hand and transfers it to your cold butter.
While the phrase "like a hot knife through butter" is a well-known one, most people rarely go through the trouble of actually heating a knife, with the SpreadTHAT butter knife you won't have to go through any trouble either.
