Know before you buy
The hollow-edge, or granton edge, features small indentations along the blade that create tiny air pockets. This reduces friction and prevents starchy or moist foods from sticking to the side of the blade while you slice.
A bolster-free design means there is no thick metal shoulder where the blade meets the handle. This allows you to sharpen or hone the entire length of the blade edge, making it much easier to maintain the knife's performance over time.
RWL34 is a high-performance powdered steel known for its exceptional edge retention and toughness. Because it undergoes a precise 6-stage heat treatment to reach 61 Rockwell hardness, it holds a razor-sharp edge significantly longer than typical kitchen knife steels.
Yes, the knife features a symmetrical, contoured handle designed for ambidextrous comfort. It provides a secure, ergonomic grip regardless of which hand you use.
NSF certification indicates that the knife meets rigorous standards for public health, safety, and sanitation. While often required in professional kitchens, it serves as a reliable benchmark for home cooks that the materials and construction are durable and food-safe.
A 16-degree angle is quite sharp and optimized for precision cutting. To maintain this edge, avoid cutting on glass, stone, or ceramic surfaces, and use a high-quality honing rod regularly to keep the edge aligned.
