250mm Gyuto Asymmetrical B-Grind Koa
This handmade kitchen knife is truly one of a kind, meticulously crafted by artisanal knife maker Dan Bidinger to showcase both form and function. Drawing inspiration from the classic Japanese Gyuto, the blade’s profile offers superb versatility in slicing, dicing, and chopping. Every angle, curve, and surface is deliberately designed to promote comfort, efficiency, and precision for chefs of every skill level. The asymmetrical B grind that Dan pioneered sets this knife apart from typical Western or Japanese blades, incorporating both a wide fuller at the top of the blade and a secondary narrow fuller along the right face. These fullers dramatically reduce weight while minimizing drag, ensuring that slices glide smoothly and ingredients release swiftly. Constructed from CPM 3V steel—one of Dan’s personal favorites—this blade boasts exceptional sharpness potential and remarkable edge retention, making it a formidable tool for the discerning cook. The result is a knife whose geometry and steel composition stand as a testament to thoughtful craftsmanship and a deep understanding of culinary needs.
Dan’s proprietary asymmetrical B grind is widely revered as one of the best geometries for both professional and home kitchens, elevating food preparation to an art form. The wide fuller not only lessens overall blade mass but also helps channel away ingredients to prevent sticking. Meanwhile, the secondary narrow fuller on the right side fine-tunes these effects, allowing for effortless control as you push or pull through various textures. This careful engineering perfectly aligns with CPM 3V’s resilient characteristics, delivering strength without compromising on lightness or edge stability. Repeated sharpening sessions are kept to a minimum, as the steel’s high wear-resistance means it holds a keen edge far longer than many other alloys. For those who wish to learn more about the specialized qualities of CPM 3V, a quick web search reveals its esteemed reputation among knife enthusiasts. In every sense, this geometry and steel pairing creates an agile, precise, and durable blade that stands head and shoulders above typical production knives on the market.
Complementing the exquisite blade is a classic tapered full tang handle, shaped in a timeless coke-bottle contour that feels luxuriously ergonomic. Crafted with breathtakingly figured Koa scales, the handle adds warmth and visual appeal to the knife, giving a singular piece a touch of uniquely natural beautiful. The ultra-fine tapered tang not only enhances balance but also contributes to the knife’s elegant silhouette, ensuring it rests naturally in the hand without causing fatigue during extended prep work. This thoughtful union of materials, geometry, and design results in a rare masterpiece that both collectors and culinary professionals will cherish for years. From the asymmetrical B grind to the premium CPM 3V steel and the stunning Koa handle, every element of this singular creation exemplifies Dan Bidinger’s commitment to pushing the boundaries of artistry and performance in kitchen cutlery.

Product Care:
Cleaning: Clean by hand with warm water. Avoid wetting the handle when possible.
Sharpening: We advise using whetstones to sharpen your knives and a honing rod or steel to maintain the burr between sharpening sessions.
Reactive Steels: Reactive steels like Aogami Super, Apex Ultra or one of the many premium reactive German and Swedish steels are susceptible to rust if not properly cared for. In this case we advise that you keep the knife dry between uses and when storing the knife for longer periods wiping the knife blade with Tsubaki oil or another food safe oil is a wise choice. This will not stop a patina forming on the blade, but it will stop rust. A patina can be a beautiful personal feature on your knife and helps to stop rust forming. So, dry your knife regularly between uses, store in a dry place and apply some Tsubaki oil from time to time when storing for long periods.

Handle Care: If you have a knife with a non-stabilised wooden handle, you can apply Tsubaki oil or another food safe oil to your handle from time to time. Food safe wax can be applied to both stabilised and no-stabilised wooden handles. Never apply hot wax or oil as you risk warping or damaging the handle.
