Forged in Sakai, Japan by master blacksmith Yoshikazu Tanaka, the core steel on this HADO Sumi Bunka 180mm is Hitachi Metals Yasuki Specialty Steel (YSS) Shirogami Two. The steel takes a fantastically sharp edge and is easy to maintain.

The knife features a San Mai or 3-layer construction with the Shirogami steel protected by an iron cladding. Ground and sharpened by HADO knives’ Tadataka Maruyama, the spine thickness is consistent up until the primary bevel, which then tapers very quickly towards the tip giving the knife a very stable feel. A wide bevel, flat ground knife, these blades are super sharp and thin behind the edge. Pressing your fingernail against the edge you will notice a little flex, demonstrating just how thin and sharp these knives are.

Tadataka-San has done an amazing job in terms of fit and finish and each knife features a beautifully polished and rounded spine and artfully ground, angular choil. A blend of textures on the face of the blade help to highlight the three-layer San Mai construction. Beautiful, dark black Kurouchi drifts into a misty Kasumi before hitting the satiny mirror polished edge band.

A traditional octagonal shaped, hidden tang handle, with a luxurious feeling, natural wax finish pairs beautifully with the stunning, yet rustic blade.

This is a very classy knife featuring amazing fit and finish, world class grind and a beautiful, tasteful design.

Blade type

Bunka

文化

A close cousin of the santoku, distinguished by its reverse-tanto tip — an angular k-tip where the spine drops sharply to meet a mostly flat edge. The flat profile excels at push cutting, and the aggressive tip gives back the fine point work a santoku's rounded nose gives up, making the bunka a versatile mid-length all-rounder with a distinctive silhouette.

The bunka's appeal is as much geometry as style: the angular tip is excellent for detail and scoring but asks for a little respect, since the point sits lower and sharper than on a curved blade. Performance otherwise tracks the santoku closely, so the choice between them usually comes down to tip preference and how the knife feels in the hand.

Cutting edge steel

Shirogami #2

Pure plain carbon steel

Typical HRC
62–65
Corrosion class
Carbon
Production
Conventional
Origin
Japan (Hitachi YSS / Proterial)

Shirogami #2 — White Paper #2 — is a hair less carbon-heavy than its sibling and substantially more user-friendly. About 1.05 to 1.15 percent carbon with the same restrictive impurity controls makes it the most-asked-for white paper in working kitchen knives, particularly in the Sakai and Tosa traditions.

For the cook, White #2 is the steel that defines what a clean carbon edge feels like: a fast burr that wipes off cleanly, a glassy refined apex, and the kind of feedback at the stone that most makers consider a benchmark for the apprentice. It runs at 62–64 HRC, holds an edge longer than 1084 but less than 52100 or Aogami #1, and is genuinely as easy to sharpen as any kitchen knife steel in current use.

It will patina readily and rust if neglected, and it is unforgiving of the dishwasher in the way every clean carbon is. In return, it offers one of the most direct, satisfying experiences a hand-finished kitchen knife can deliver. Among the makers Modern Cooking carries, Yoshikane Hamono, Masamoto Sohonten, and Hado Knives work in Shirogami #2. White #2 is — alongside Aogami #2 — the most representative of the Hitachi tradition.

Blade construction

Laminated Steel

A category covering knives built from multiple layers of different steels forge-welded together. The hard cutting steel is sandwiched between softer outer layers (cladding) that protect the core, add toughness, and often contribute visual contrast.

The most common laminated constructions in the Modern Cooking catalogue are:

SanMai (三枚) — three layers: hard cutting steel in the centre, softer cladding on both sides. The traditional and most common form.

GoMai (五枚) — five layers: a hard core, two intermediate layers, and two outer layers. Adds visual depth and structural complexity.

KuMai (九枚) — nine layers: similar logic, with more cladding layers for additional pattern and structural variation.

GoMai and KuMai are often chosen not only for the additional layers and visual depth, but also because the intermediate layers can act as a nickel diffusion barrier — limiting carbon migration out of the core into the cladding during forge welding, and protecting the core's intended carbon content through the heat of the forging process.

In all cases the cutting performance is determined by the core steel; the outer layers are cosmetic and structural. The lamination contributes corrosion protection (when a stainless jacket clads a carbon core), reduced reactivity, and the visible boundary between core and cladding that gives the knife its character.

Grind

Flat

A grind in which the blade tapers in a straight line from the spine down toward the edge, with no curve or hollow in the bevel. The flat grind is the most common geometry on modern double-bevel kitchen knives because it balances cutting performance and durability: thin enough behind the edge to slice well, with enough steel behind it to stay strong.

A true full flat grind, running from spine to edge, is keen but can wedge in dense produce as the food meets the widening blade; many kitchen knives use a partial flat grind that begins lower on the blade to manage that. The flat grind's appeal is its predictability — it sharpens straightforwardly, behaves consistently, and asks nothing unusual of the user.

Handle construction

Hidden Tang

A construction in which the tang runs into the handle but stays concealed inside it, rather than showing between two scales. A narrower tang — a full-length stick or a shorter projection — is set into a drilled or burned channel in a one-piece handle and secured with adhesive, a friction fit, or a threaded fitting drawn up against the blade. This is the traditional construction of Japanese wa-handles and many European hidden-tang knives.

The design puts the handle material in charge of the look and feel: a single piece of wood, horn, or composite — often with a ferrule or spacers at the front — is shaped into any cross-section the maker wants, from the classic octagonal and D-shaped wa profiles to fully rounded Western forms. With no steel showing along the grip, the handle can be slim and light, and is frequently made to be removed and replaced, with the balance sitting toward the blade.

Product Care

Cleaning: Clean by hand with warm water. Avoid wetting the handle when possible.

Sharpening: We advise using whetstones to sharpen your knives and a honing rod or steel to maintain the burr between sharpening sessions.

Reactive Steels: Reactive steels like Aogami Super, Apex Ultra or premium reactive German and Swedish steels are susceptible to rust if not properly cared for. Keep the knife dry between uses and when storing for longer periods, wiping the blade with Tsubaki oil or another food-safe oil is a wise choice. A patina can be a beautiful personal feature on your knife and helps to stop rust forming.

Handle Care: For non-stabilised wooden handles, apply Tsubaki oil or another food-safe oil from time to time. Food-safe wax can be applied to both stabilised and non-stabilised wooden handles. Never apply hot wax or oil as you risk warping or damaging the handle.
