  3. Kai Japan - Shun Premier Tim Mälzer TDM-1784 - Small Kiritsuke 15cm - 13 The Lucky Edition - kitchen knives

    Kai Europe offers another exclusive collaboration with master-chef Tim Mälzer: Small Kiritsuke 13 The Lucky Edition.

    A special edition with an opaque brown handle and a 15 cm hammered blade. The edition is limited to only 5555 pieces and each one is numbered. As such, each knife is a unique collector's item.

    As with the previous limited edition, the Kiritsuke was chosen, but in a smaller size. This is a type of Japanese knife that combines the design and characteristics of a usuba and a yanagiba. The usuba is used for cutting vegetables and the yanagiba for raw fish, for example when making sashimi. As such, the kiritsuke can be used for many different tasks in the kitchen: cutting vegetables, meat and fish. The tanto inverted profile makes the tip very flexible and perfect for precision tasks. The flat blade is perfect for other cutting tasks.

    The superbly sharp blade is made of VG MAX steel with a hardness of 61 (± 1) HRC and surrounded by 32-layer Damascus steel. The Damascus steel makes each knife unique. The matt handle of this special edition is, like the regular knives in the Tim Mälzer Premier collection, made of walnut wood: it is moisture-resistant thanks to the resin treatment. The chestnut shape of the handle is comfortable in the hand and provides a firm grip when using the knife. 

    Blade: Damascus stainless steel VG MAX hardness of 61±1 HRC
    Handle: Matt walnut wood
    Blade length: 155 mm.
    Handle length: 120 mm.
    Blade thickness: 1.9 mm.
    Total length: 285 mm.
    Weight: 151 g.
    Notes: not dishwasher safe - wooden presentation box

Kai Knives FAQ

What is the difference between Kai Shun and Kai Wasabi?

The Shun series represents the top of the range: Damascus steel, VG-MAX core, and high hardness. The Wasabi series is more essential and robust, designed for daily professional use with an excellent quality/price ratio.

How to maintain Kai Damascus steel knives?

Always wash by hand and dry immediately. For sharpening, Japanese water stones with medium-fine grit (1000–6000) are recommended, avoiding dishwashers and aggressive detergents.
