TOJIRO has been making knives in Tsubame, Niigata Prefecture since 1955 - one of Japan dedicated metalworking cities, known for producing everything from cutlery to medical equipment with the same precision-manufacturing heritage. The Color Series is the workhorse line of the TOJIRO catalog: molybdenum vanadium stainless steel, mono construction, thin grind, and a comfortable antibacterial elastomer handle in a range of colors. These are the knives that professional kitchens reach for when they need reliable performance, easy maintenance, and a handle color that stands out on a busy line.
The 150mm petty is the larger of the two Color Series petty sizes - long enough for comfortable board work while still suited for in-hand tasks. At 150mm it bridges the gap between a compact detail knife and a full-size chef knife, handling trim work, citrus, herbs, and small vegetable prep efficiently. The white handle is clean and neutral - easy to keep visually clean and a practical choice for kitchens that prefer a classic look.
The steel is molybdenum vanadium stainless - a fine-grained, tough alloy widely used in commercial kitchen knives for its combination of corrosion resistance, durability, and ease of sharpening. Heat-treated to 57-59 HRC, it holds a solid working edge through sustained kitchen use and resharpens quickly on quality water stones or a ceramic rod. The thin grind improves cutting efficiency across all tasks. The antibacterial elastomer handle is dishwasher-safe in theory but hand washing is always recommended to extend handle and blade life.
Care Instructions: Hand wash and dry after use. Avoid the dishwasher for best longevity. Use a wood or soft synthetic cutting board. Avoid bones, frozen foods, and hard surfaces to protect the edge. Sharpen on quality water stones or a ceramic rod.
