Kokoro Blade Infinity Edition Kiritsuke (8-Inch, Damascus Steel)

What makes the dual cutting core different from standard knife construction?

The dual cutting core combines two distinct steel types - 10Cr15CoMoV and 9Cr18MoV - each contributing specific properties. The 10Cr15CoMoV provides excellent edge retention and sharpness, whilst the 9Cr18MoV offers superior corrosion resistance. This fusion creates a cutting edge that maintains sharpness longer than single-steel blades whilst resisting staining and corrosion from acidic foods.

How does the Kiritsuke design differ from a standard chef knife?

The Kiritsuke features a longer, flatter profile compared to traditional chef knives, with a distinctive angled tip. This design excels at precision slicing techniques using a push-cutting motion rather than rocking. The flatter blade provides more contact with the cutting board, making it ideal for slicing proteins, vegetables and creating precise cuts for presentation work.

What maintenance does the Damascus steel require?

Hand wash immediately after use with warm soapy water and dry thoroughly to prevent water spots on the Damascus pattern. Avoid dishwashers as the harsh detergents and heat can damage the blade finish. Apply a thin layer of food-safe mineral oil occasionally to maintain the Damascus pattern's appearance and prevent any potential oxidation.

Is this knife suitable for beginners or only experienced cooks?

Whilst the Kiritsuke design traditionally requires some skill to use effectively, this knife's balanced construction and sharp edge make it accessible to intermediate cooks. Beginners should practice proper cutting techniques, particularly the push-cutting motion that works best with this blade profile. The exceptional sharpness means less pressure is needed, actually making cuts easier once proper technique is learned.

How sharp is the blade out of the box?

The blade arrives with a 250-300 BESS rating, which is considered razor-sharp. This level of sharpness will easily slice paper and effortlessly cut through tomatoes without crushing. The initial sharpness should last several months with regular home use before requiring professional sharpening, depending on cutting technique and frequency of use.

What cutting tasks is this knife best suited for?

The Kiritsuke excels at precision slicing of proteins, vegetables and fruits. It's particularly effective for creating thin, uniform slices of fish for sashimi, slicing roasts and preparing vegetables for stir-fries. The flat profile also makes it excellent for chopping herbs and creating brunoise cuts. It's less suitable for heavy-duty tasks like breaking down whole chickens or cutting through bones.

How should I store this knife to maintain its condition?

Store the knife in the provided wooden box when not in regular use, or use a magnetic knife strip to prevent blade contact with other utensils. Avoid storing in drawers where the blade can knock against other items. A knife block with individual slots works well, but ensure the slot doesn't scrape the Damascus pattern. Always ensure the blade is completely dry before storage.

What's included with the knife purchase?

The knife comes in a luxury black wooden gift box etched with the Kokoro logo and lined with red fabric. The presentation box is suitable for gift-giving and long-term storage. No additional accessories like sharpening tools or cutting boards are included - the focus is on delivering a premium knife with elegant presentation packaging.
