Who it fits

Key specs explained for this knife

Blade Length: 7"

This length offers a versatile cutting surface that handles most kitchen tasks. You can slice vegetables, dice herbs, and portion proteins with ease. It fits comfortably in standard knife blocks and storage spaces. The size balances control and reach, making it a practical choice for daily meal preparation without being too large for smaller hands.

Blade Hardness: 66 HRC

A Rockwell hardness of 66 indicates ultra-hard steel. This level of hardness allows the edge to stay sharp longer than softer blades. You will experience fewer sharpening sessions during regular use. However, harder steel can be more brittle, so you should avoid using this knife on bones or frozen foods to prevent chipping.

Blade Material: MC66 steel

MC66 is a high-carbon stainless steel developed by Miyabi. It combines the durability of stainless steel with the sharpness potential of high-carbon alloys. The material resists corrosion while holding a fine edge. This makes it suitable for acidic ingredients like tomatoes or citrus, which might stain or damage lower-quality steel over time.

Edge Angle: 9.5° to 12°

This narrow angle creates a very thin, precise cutting edge. You will notice cleaner slices with less tearing of delicate foods like fish or herbs. The angle is sharper than standard Western knives, which often sit around 20 degrees per side. This precision enhances control, though it requires careful handling to maintain the fine edge.

Construction: 49-layer Damascus

The blade is forged from 49 layers of steel, creating a distinctive pattern. This construction typically improves corrosion resistance and edge retention compared to single-steel blades. The layers also add structural integrity. You get a unique visual appearance with each knife, as the pattern varies. It signals traditional craftsmanship and a focus on both performance and aesthetics.

Design and build details

The listing describes a 49-layer Damascus construction that creates a unique Moonlight pattern on the blade. This is not just cosmetic. The layers bond MC66 stainless steel, which reaches 66 HRC hardness. The CRYODUR ice-hardening process supports this durability. You get a blade that holds an edge longer than softer steels. The edge is hand-sharpened to a precise 9.5° to 12° angle using traditional Honbazuke honing. This steep angle provides a fine, sharp cutting line for delicate tasks. The finish divides the blade surface from the edge seamlessly, which may help with food release.

The handle is made from dark maple wood, shaped by hand. It connects to a 7-inch blade. The total length is 12.5 inches, with a width of 1 inch and a height of 2 inches. The knife weighs 7.04 ounces. This weight is moderate for a santoku. It should feel balanced in your hand during extended prep work. The wooden handle offers a classic look and grip. You must hand-wash this knife to protect the wood and the steel. The listing notes it is made in Seki by master artisans.
