The specific Japanese kitchen knife — its specific form, its specific steel, its specific geometry — is among the most discussed and most admired of all Japanese craft objects, and the specific attention that the international food media has given to Japanese knife making over the past decade has made Sakai, Seki, and Tsubame-Sanjo recognisable names to a specific international audience of professional cooks and serious home cooks who might otherwise have never encountered the specific names of specific Japanese cutlery towns.
But the specific knife — however beautiful, however well-made — is only the instrument. The specific knowledge of what to do with it is the specific skill that the specific knife enables, and the specific Japanese cutting tradition is a specific body of technical knowledge whose specific depth and specific variety are not widely understood even by people who have considerable familiarity with Japanese food culture.
The specific Japanese cutting techniques — the specific named cuts, each with its specific angle, its specific specific pressure distribution, and its specific specific intended result — are not mere refinements of a generic cutting action. They are specific specific technical solutions to specific specific problems about how to transform specific specific raw ingredients into specific specific forms that serve specific specific cooking functions and produce specific specific eating experiences that other cutting approaches do not achieve.
The Japanese Knife Tradition: A Brief Foundation
Before describing the specific cutting techniques, the specific knives that execute them deserve brief attention, because the specific tools and the specific techniques are inseparable — the specific Japanese cutting tradition developed with the specific Japanese knife’s specific geometry in mind, and the specific techniques are optimised for the specific single-bevel (片刃 — kataba) construction that most traditional Japanese kitchen knives use.
The specific single-bevel construction: a traditional Japanese kitchen knife has a specific flat back (the specific ura — 裏) and a specific bevelled cutting edge on one side only (the specific omote — 表). This specific construction — contrasting with the specific double-bevel (両刃 — ryōba) of most Western kitchen knives — produces a specific specific geometry whose specific specific cutting action is different from the double-bevel equivalent. The specific specific single-bevel knife cuts with a specific specific pulling and guiding action rather than the specific specific wedging action of the double-bevel, and this specific specific cutting action produces the specific specific clean, precise cuts — particularly the specific specific thin cuts and the specific specific decorative cuts — that the specific specific Japanese technique requires.
The specific primary Japanese kitchen knives:
Yanagiba (柳刃 — willow blade): the specific long, thin, single-bevel sashimi knife whose specific specific thirty-to-thirty-five centimetre blade executes the specific specific long-pull sashimi cut in a single drawing motion. The specific specific Japanese philosophy of sashimi cutting: the specific specific ideal sashimi cut makes clean contact with the specific specific fish flesh through a single drawing motion rather than multiple back-and-forth cuts, because each additional contact disrupts the specific specific cellular structure of the specific specific fish flesh and affects the specific specific texture that the specific specific sashimi presents.
Deba (出刃 — pointed blade): the specific specific heavy, thick-spined filleting knife whose specific specific weight and specific specific geometry allow it to execute the specific specific filleting cuts and the specific specific bone-cutting actions that the specific specific fish preparation requires.
Usuba (薄刃 — thin blade): the specific thin, flat-bladed vegetable knife whose specific specific straight cutting edge and specific specific thin profile execute the specific specific specific decorative vegetable cuts and the specific specific specific paper-thin vegetable preparations that the specific specific Japanese professional vegetable preparation tradition requires.
The Decorative Cuts: Kazarikiri
Kazarikiri (飾り切り — decorative cutting) is the specific tradition of Japanese vegetable carving — the specific cutting of vegetables and other ingredients into specific decorative forms that serve both visual and functional purposes in the specific kaiseki and the specific formal Japanese meal presentation context.
Katsuramuki (桂剥き — rotary peeling). The specific specific most celebrated of all specific specific Japanese vegetable cutting techniques — the specific specific technique of holding a specific specific cylindrical vegetable (daikon is the specific specific standard practice material, cucumber the specific specific more advanced, carrot the specific specific most difficult) against the specific specific usuba blade and rotating the specific specific vegetable while maintaining the specific specific cutting contact, producing a specific specific continuous, unbroken sheet of the specific specific vegetable whose specific specific target thickness is the specific specific specific paper-thin standard of the specific specific professional kitchen.
The specific specific quality standard: the specific specific katsuramuki sheet at the specific specific professional standard should be thin enough that the specific specific text of a specific specific newspaper is readable through it when held to the light. This specific specific specific thinness — which requires the specific specific specific precise control of the specific specific specific cutting angle and the specific specific specific uniform rotation speed that only the specific specific specific accumulated practice of the specific specific specific specific professional training produces — is the specific specific benchmark that the specific specific specific Japanese culinary school uses to evaluate the specific specific specific vegetable cutting skill of the specific specific specific student.
Sasagaki (笹掻き — bamboo-leaf shaving). The specific specific technique for burdock root (gobō) and for specific specific other fibrous root vegetables — the specific specific method of drawing the specific specific vegetable against the specific specific knife blade in a specific specific shaving motion that produces the specific specific thin, curled, irregular pieces whose specific specific surface area and specific specific shape allows them to cook faster and absorb flavour more completely than the specific specific same vegetable cut in any other way. The specific specific name: the specific specific resemblance of the specific specific shaved pieces to the specific specific bamboo leaves that fall in specific specific autumn.
Hyōshigi-giri (拍子木切り — oblong cut). The specific specific rectangular cut — typically 3cm × 1cm × 1cm — used for the specific specific specific root vegetables, the specific specific tofu, and the specific specific specific other firm ingredients where the specific specific particular oblong form creates the specific specific specific cooking surface and the specific specific specific structural character that the specific specific preparation requires.
Ran-giri (乱切り — tumble cut). The specific specific rolling cut — the specific specific specific technique in which the specific specific vegetable (typically carrot, burdock, lotus root, or various specific specific other root vegetables) is rolled a quarter-turn between each cut while the specific specific knife descends at the specific specific specific consistent angle, producing the specific specific irregular, multi-faceted pieces whose specific specific specific large and varied surface area absorbs cooking liquid more completely than the specific specific specific uniform pieces of a standard rectangular cut.
The Sashimi Cuts: Tsukuri
Tsukuri (作り — the making, used as the professional term for sashimi cutting and presentation) encompasses the specific specific range of cuts applied to specific specific different fish and specific specific different presentations in the specific specific sashimi tradition.
Hira-zukuri (平作り — flat cut). The specific specific standard sashimi cut — the specific specific cut in which the specific specific yanagiba descends at the specific specific perpendicular to the specific specific fish’s specific specific fibre direction, with the specific specific specific long drawing motion, producing the specific specific rectangular slice of specific specific consistent thickness (typically 7-10mm) that constitutes the specific specific standard sashimi piece.
Sogi-zukuri (削ぎ作り — angle cut). The specific specific angled cut used for the specific specific specific flat fish (hirame — flounder, karei — sole) whose specific specific specific flesh is thin and benefits from the specific specific specific angled cut that increases the specific specific specific surface area of each piece. The specific specific knife descends at the specific specific specific acute angle rather than the specific specific specific perpendicular of the hira-zukuri, and the specific specific specific resulting piece is larger, thinner, and has the specific specific specific specific translucent quality that makes the specific specific specific flat fish sashimi one of the specific specific specific most visually distinctive of all specific specific specific sashimi presentations.
Ito-zukuri (糸作り — thread cut). The specific specific extremely fine julienne cut used for the specific specific specific squid (ika) and the specific specific specific sea bass (suzuki) sashimi preparations — the specific specific specific drawing cut that produces the specific specific specific fine threads of the specific specific specific fish flesh whose specific specific specific texture is completely different from the specific specific specific same fish cut in any other way. The specific specific specific squid ito-zukuri — in which the specific specific specific thin threads of the specific specific specific white squid flesh are arranged in the specific specific specific pile that presents as the specific specific specific most elegant of all sashimi presentations — requires the specific specific specific specific control of the specific specific specific yanagiba’s specific specific specific cutting angle and the specific specific specific fish’s specific specific specific fibre direction that only the specific specific specific experienced hand achieves.
