ONJIN (温刃) -Butter Knife Hard butter melts with your body warmth. Pure silver delivers a stress-free morning. Your Warmth, Perfect Spread.

【What You Will Experience】
Fresh baguettes and croissants, never crushed.
Cold butter straight from the refrigerator gradually softens to perfect spreadability—simply by holding the knife. Your body warmth does the work.
A small daily frustration transforms into an elegant moment.
Solving the Universal "Hard Butter Problem"
Anyone who loves bread and butter knows this moment.
Hard butter tears the bread. Waiting is tedious.
ONJIN solves this universal problem using the simplest energy source: your body warmth.

【Why Pure Silver?】
・Thermal conductivity: 420 W/(m·K) — 26 times that of stainless steel.
Your hand's warmth instantly transfers to the blade edge.

・Calculated design
The thin blade efficiently conducts heat. The hammered handle provides slip resistance, comfortable grip, and heat retention.

Self-Contained Solution, No Power Required
ONJIN needs no external power source or battery.
Only your body warmth—the most natural and sustainable energy source.
Simply hold it, and the blade warms to gently soften butter.
Elegant problem-solving without technology.
