Santoku
A Japanese general-purpose knife combining three traditional blade virtues.
The santoku bōchō (Japanese: 三徳包丁; lit. 'three virtues knife' or 'three uses knife') is a general-purpose kitchen knife originating in Japan. Its blade is typically between 13 and 20 centimeters long, with a flat edge and a sheep's foot-tipped blade that curves down at an angle approaching 60 degrees at the point. The term santoku may refer to the wide variety of ingredients the knife can handle—fish, meat, and vegetables—or to the tasks it can perform: chopping, dicing, and slicing, with either interpretation indicating a multi-use, general-purpose kitchen knife. Note that the bunka bōchō (文化包丁) is a distinct subtype with a different blade profile, not a direct synonym.

Lore & Background
The santoku knife design originated in Japan, where traditionally a deba knife is used to cut fish, a gyuto knife is used to cut meat, and a nakiri knife is used to cut vegetables. The term bunka bōchō means 'cultural knife,' referring to a modern, Western-influenced design, not to 'cultural food.'
Reader's Guide
The santoku is significant as a versatile kitchen knife that merges Japanese and European design elements. Its blade geometry incorporates a sheep's foot tip, which provides a more linear cutting edge with limited rocking travel compared to a German or Western-style chef's knife. The santoku is shorter, thinner, and lighter than a traditional European chef's knife, with more hardened steel in the tradition of Samurai sword steel to compensate for thinness. It typically incorporates a European-style bilateral cutting edge but maintains a more extreme 12 to 15 degree shoulder, akin to Japanese cutlery. This harder, thinner steel holds its edge longer but is more likely to chip if misused. Santoku knives usually have no bolster, sometimes incorporate fluted sides (Granton edge), and maintain uniform thickness from spine to blade edge. Higher-quality versions may use san mai laminated steels, including suminagashi patterns, for improved strength and rust resistance. Many copies made outside Japan have substantially different edge designs, balance, and steels.
