Kevnhaun was founded in Osaka, Japan, by master cutlers who saw a problem: modern life makes even simple tasks like spreading butter on toast feel frustrating. They asked, why should a dull knife or a flimsy handle stand between you and a perfect breakfast? Our team spent 3 years developing this specific 147mm length, testing over 50 handle prototypes with chefs and home cooks. Every knife is forged from a single piece of SUS304 Japanese stainless steel, certified by the Japan Stainless Steel Association, and undergoes a 12-step hand-finishing process. The result isn't just a tool; it's the end of the struggle with hard butter and crumbling bread. It's now the top-rated butter knife in its category for 24 consecutive months, chosen for its unwavering performance.

The Kevnhaun 147mm Premium Stainless Steel Butter Knife is crafted from high-quality stainless steel, specifically 18/10 stainless steel, which comprises 18% chromium and 10% nickel. Chromium is included to provide exceptional corrosion resistance, preventing rust and tarnish even with frequent exposure to moisture and acidic foods, while nickel enhances durability and adds a lustrous, polished finish that maintains its appearance over time. The ergonomic handle is typically made from food-safe materials such as ABS plastic or thermoplastic rubber, designed to offer a comfortable, non-slip grip that reduces hand fatigue during use and ensures precise control when spreading. This combination of materials ensures the knife is dishwasher-safe for easy cleaning, hygienic due to stainless steel's non-porous surface that resists bacterial growth, and built for long-lasting performance in daily kitchen tasks, making it an efficient and reliable tool for spreading butter, cheeses, and other soft foods with smooth, even results.
