The Tojiro DP collection is a combination of traditional Japanese techniques along with today's advanced technology producing multi-layered razor sharp blades. The Tojiro DP knives feature a full-tang 3-layered blade construction. The core is made of a high quality VG-10 steel and it is encased by two layers of rust resistant stainless steel. This results in a 60 degree Rockwell Hardness, and provides a 9 degree to 12 degree blade angle for ideal sharpness. The triple riveted traditional style handle is made of eco-friendly material which has less shrinkage with age-related deterioration; which means less cracks and loosening on the handle. The handle has the perfect balance and the short bolster collar allows for full and complete sharpening of the blade. Every knife is meticulously hand finished by artisan craftsmen. The Tojiro DP series offers a large selection of blade shapes and sizes for all of your culinary needs. Made in Japan, Lifetime Warranty.
