ZDP-189 is a powdered stainless steel produced by Hitachi that achieves 65+ HRC through a grain structure only powder metallurgy can produce. The edge retention is exceptional - significantly above what any conventional steel achieves at comparable hardness. Katsuto Tanaka at Tanaka Kama Kogyo in Omura City, Nagasaki Prefecture applies his fourth-generation forge-welded technique to this demanding steel, producing a blade that combines the premium performance of ZDP-189 with the distinctive Matsubara character.
The ZDP-189 Damascus 210mm Gyuto is the premium chef knife in the Matsubara lineup - the finest steel, the finest cladding, and the personal attention of Katsuto Tanaka on the finishing. The stainless Damascus cladding and exceptional edge retention make this knife a worthwhile investment. The even, double-bevel grind and octagonal handle will suit both right- and left-handed users well.
Care Instructions: ZDP-189 is a fully stainless powdered steel - low maintenance and resistant to corrosion. Hand wash and dry after each use. Avoid the dishwasher, and use wood or rubber cutting boards only. Avoid bones, frozen foods, and hard materials - at 65+ HRC, the edge is extremely hard and chips more easily than softer steels if misused. Sharpen on quality water stones with consistent angle and light pressure. Strop regularly to maintain the edge between sharpenings.
Each knife is made by hand so measurements may vary.Blacksmith: Katsuto Tanaka
