Why Choose Butterfork? Engineered for Effortless Performance in Every Cut.

Our founder is a knife enthusiast and a foodie. Over the years, he has been on a quest for the ideal chef's knife—one that is affordable for the average household without being prohibitively expensive,one that at the same time, maintains a high quality and a good user experience.

Many of us may have had disappointing experiences when using knives in the kitchen: sometimes a knife would quickly become blunt, forcing us to sharpen it frequently; sometimes the blade was too prone to break or bend when cutting; and sometimes we didn't want to spend too much money on another knife...

We hope to combine the advantages of the existing knives on the market, improve the problems that may arise during use, and create a knife with high quality and good value for money, which everyone can feel confident about purchasing and use. We start to focused on the steel used for making knives and conducted research on the performance of different steels as kitchen knives.Being as sharp as possible isn't necessarily best, particularly if you're trading off the knifes ability to retain that sharp edge.This prevalent issue affects both home cooks and professional chefs alike.Choosing a steel that balances sharpness, edge retention, and durability within a budget is an agonizing decision. 

After two years of comparing steels and testing hundreds of options, we finally set our sights on AR-RPM9, the steel consistently used by CJRB. This steel delivers everything we could want for our butterfork kitchen knives.

AR-RPM9 Steel  is meticulously crafted from a proprietary blend of elements, including Carbon (C), Chromium (Cr), Molybdenum (Mo), Vanadium (V), Cobalt (Co), Manganese (Mn), Silicon (Si), and Nickel (Ni). The result? This innovative high-carbon stainless steel holds an incredible edge and won’t corrode like other high carbon steels. A knife that stays sharp 2.78x longer than average standard.

After that, We conducted extensive research, collaborating with renowned chefs, top designer and blade Manufacturer to create the most thoughtfully designed kitchen knife available. The outcome is a remarkably sharp, thin, and resilient blade that embodies the perfect fusion of cutting-edge technology, ergonomic design, and traditional craftsmanship.

A long deep belly of the Purest Chef's Knife helps with effortless chopping, while the lowered tip makes slicing and finer work more approachable. The blade is then tapered to a 23 degree edge angle, allowing you to effortlessly slice through hard carrots, create precise cuts of fresh cucumbers, and handle delicate salmon fillets without damaging their texture.

At the same time, Considering the modern kitchen's aesthetic and individual preferences for color, we have introduced a design with interchangeable knife handles. Currently, we offer six ABS handle options. We will continue to expand our selection with different materials and colors to complement the styles of our users' home kitchens.

How to Maintain Superior Edge Retention？This is determined by several factors. 1- alloy composition (Vanadium forms some of the hardest carbides), 2- Rockwell hardness, and 3- ability to resist various impacts that could deform the edge. AR-RPM9 Steel, at 60RC, has better edge retention than the top of the line Japanese steel, SG-2 at 63RC. SG-2 is Japan's gold standard Powder Steel. Not only is AR-RPM9 Steel more wear-resistant (decent proxy for edge retention), but it's also tougher.
