Alexandra, Victoria, Australia · High Performance Japanese-Influenced Kitchen Knives

Mark Cordina

Cordina Customs

Mark Cordina builds high-performance kitchen knives as Cordina Customs from his workshop in Alexandra, Victoria. He came to knifemaking in 2020 after working as a stainless steel fabricator/specialist, alongside experience in building and professional cooking as a chef de partie. This background brought both a fabricator’s discipline and practical kitchen knowledge to his Japanese-influenced culinary knives. His work spans forged mono-steel, San Mai, copper-clad and honyaki constructions, with 26C3 among his favoured steels and ebony and highly figured timbers recurring at the handle. Functional first and increasingly ambitious in execution, these are knives made to be used, kept and handed on.

About the maker

On the workshop

Alexandra sits in the Goulburn Valley, about two hours north-east of Melbourne, and it is from a workshop there that Cordina Customs has run since 2020. Before making knives, Mark Cordina worked as a stainless steel fabricator/specialist, producing repeat-process and architectural feature work requiring fine detail, low tolerances and stainless finishes completed to a very high specification. When his outdoor education work stopped during the lockdowns, he made his first knife from a discarded industrial hacksaw blade and shed offcuts, then entered a maker competition with his second.

On the workshop

During the first years of establishing Cordina Customs, Mark also worked as a chef de partie in a fine-dining restaurant. The kitchen gave him a practical environment in which to test developing profiles and geometries. His early knives were flat ground, but experience, testing and a deeper engagement with Japanese kitchen knives progressively moved his work towards convex geometry with blended transitions, robust heels and purposeful distal taper while maintaining edge stability and blade rigidity.

The knives remain working tools first. Mark looks for sharpness to initiate the cut, thinness for a smooth passage through food, separation from the secondary bevel without wedging and sufficient relief above it to assist food release. His faceted, indexable handles are equally functional: an assuring hard stop at the ricasso locates the hand, a flat spine communicates blade orientation and the facets support secure use across multiple grip styles.

Cordina’s work spans forged mono-steel, San Mai, copper-clad and honyaki constructions. He uses 52100 as a robust benchmark for his Classic Series, 26C3 for a keener edge in his Deluxe Series and Hitachi steels within the Signature Series, where their performance and Japanese influence support his most complete expression of geometry, construction and finish.

For Modern Cooking, Mark Cordina belongs in the Collectors Selection as an Australian maker building knives meant to be cooked with, lived with and kept.

There is no ‘natural talent’ or ‘born with a gift’ – there is only pursuit and persistence to achieve or not.

Cutting edge steel

High-carbon tungsten-chromium-molybdenum steel

63–66
Corrosion class

Production
Conventional
Origin
Japan (Hitachi YSS / Proterial)

Aogami Super — Blue Super, in plain English — is the most heavily alloyed of Hitachi's blue-paper steels, and the one most associated with the long-edge-life end of the traditional Japanese kitchen knife world. Roughly 1.45 percent carbon, half a percent each of chromium and tungsten, plus molybdenum and vanadium additions, give it noticeably more carbide content than Aogami #2 or #1.

In a competent gyuto it typically lands at 63–65 HRC and holds an edge for an unusually long time for a non-powder steel. The trade-off, predictable from the chemistry, is that the larger carbides mean slightly more work at the stone and a slightly less smooth edge than Shirogami #1 at its peak. Most users do not notice; the ones who do tend to come from a finishing-stone tradition. Toughness is moderate — similar to or slightly below the white papers at the same hardness — and the steel will patina with normal use.

Aogami Super is the steel you reach for when you want a long-running edge from a maker who refuses to use powder metallurgy. It is widely used across the Sakai and Sanjō traditions and remains one of the most-asked-for Hitachi steels on the secondary market. Among the makers Modern Cooking carries, Neil Ayling, Konstantinos Noulis, and Jonas Johnsson work in Aogami Super. It is, in many ways, the canonical "blue paper" experience.

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.
