Z18 is a fully stainless steel with a balanced composition suited for thin-ground kitchen knives - enough hardness for a keen edge, enough toughness for daily kitchen use, and fully stainless for low-maintenance care. Tsunehisa pairs it with Damascus stainless cladding in a hammer-forged san mai construction in Tosa, Japan, producing a blade that is noticeably thin and light for its size. The Damascus pattern across the cladding gives each knife a distinctive visual character without adding complexity to the care routine.
At 187mm blade length and 46.9mm height with a 2mm spine this santoku is a well-proportioned all-purpose kitchen knife - tall enough for comfortable knuckle clearance through board work, flat enough at the heel to suit push-cutting through vegetables and proteins. At 4.8 oz it is on the lighter end for a 185mm santoku - the thin grind and light weight give it a nimble, fast feel in hand that cooks coming from heavier Western knives consistently notice immediately. The octagonal oak handle is clean and traditional.
Care Instructions: Z18 is a stainless steel - low maintenance and resistant to corrosion. Hand wash and dry after each use. Avoid the dishwasher, bones, frozen foods, and hard materials. Sharpen on quality water stones and strop regularly.
Each knife is made by hand so measurements may vary.
