German blacksmith Oliver Märtens has crafted a remarkable Nakiri that combines innovative design with superior functionality. This high-performance kitchen knife features a unique octagonal takedown handle, a new design that allows for easy maintenance and adds an element of cool sophistication. The handle is made from durable linen micarta and hand-milled anodized aluminium front and rear encaps, providing both aesthetic appeal and a secure grip. The removable handle design not only enhances the knife's practicality but also makes it a standout piece in any kitchen collection.

Known for its vegetable slicing prowess, this Nakiri boasts an edge length of 174mm. Märtens has ensured the blade is finely balanced with a beautifully tapered spine, gently narrowing from 3.45mm at the heel to 1.32mm near the tip. With a blade height of 69mm, the knife provides ample knuckle clearance for efficient chopping and slicing. Weighing in at just 246g, it is lightweight and nimble, yet sturdy, making it ideal for prolonged use without causing hand fatigue.

Constructed from Apex Ultra steel, the Nakiri's cutting edge offers exceptional sharpness and durability, with a hardness rating of 66 HRC. The blade is clad in a 200-layer Damascus that features a strikingly intricate pattern. Finished with a satin polish, the blade exudes a sleek, refined appearance. The convex grind ensures optimal cutting performance, allowing for precise and effortless slicing. Märtens' meticulous craftsmanship and innovative design culminate in a knife that is both highly functional and visually striking, making it a prized tool in any kitchen.

Blade type

Nakiri

菜切

A double-bevel vegetable knife with a tall, rectangular blade and a straight edge that meets the board along its full length. That flat profile is built for one job done exceptionally well: clean, full-contact push and chop cuts through vegetables, with the height giving knuckle clearance and a broad face to guide sliced produce. There is no belly to rock, because rocking is not what it is for.

The nakiri's specialisation is also its limit. It is superb on vegetables and unhurried prep, but the straight edge and squared-off tip make it poor at the tip work, rocking, and protein tasks a gyuto or santoku handle easily. It is best understood as a dedicated vegetable knife that earns its place alongside a more general blade rather than replacing one.

Cutting edge steel

Apex Ultra

Low-alloy fine-grain carbon tool steel

Typical HRC
64–68
Corrosion class
Carbon
Production
Conventional
Origin
Austria (developed by Tobias Hangler and Marco Guldimann; project led by Hangler at Messerschmiede Hangler)

Apex Ultra is one of the most carefully engineered non-stainless kitchen knife steels in modern circulation, and the project of an Austrian smith — Tobias Hangler — who set out, with Marco Guldimann, to design a steel for the kitchen rather than borrow one from another industry. It carries roughly 1.25 percent carbon, around four percent chromium, modest tungsten and molybdenum, and a small vanadium addition. The composition is tuned to produce a fine, evenly distributed carbide structure that supports hardness up to 67 HRC while delivering toughness comparable to 52100 at the same hardness — a combination that is the entire point of the steel.

What this means for a cook is unusual permission. You can ask a maker to grind an Apex Ultra knife thin enough that a White #1 owner would call you brave, then ask for the heat treatment to land at 65 HRC, and the resulting edge will hold for longer than Aogami Super without microchipping. It sharpens cleanly on natural and synthetic stones alike and patinas slowly because of the chromium content, though it is not stainless and should be treated as a carbon steel.

Apex Ultra has become a signature steel of the European maker community, and the Modern Cooking catalogue carries an unusually deep bench of smiths working in it. Tobias Hangler himself heads that group, alongside Marco Guldimann, Benjamin Kamon, Martin Huber, Jonas Johnsson, Karol Karyś, Birch & Bevel, and MCx. It is genuinely a step forward — one of the relatively few cases where the marketing claims and the underlying metallurgical data are saying the same thing.

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

Convex

A grind whose bevel bulges outward in a gentle curve from spine to edge, rather than running flat. That extra steel directly behind the edge makes a convex grind notably strong and resistant to chipping, while the curved geometry helps food release and lets the blade glide through dense ingredients with less wedging than a flat grind.

The strength comes at the cost of ultimate thinness and ease of maintenance. A convex edge has more metal behind it, so it is not quite as effortlessly keen as a thinly flat-ground edge, and it is harder to sharpen freehand — holding the curve takes a stropping technique or a deliberate hand rather than a single fixed angle. The reward is an exceptionally tough, smooth-cutting edge.

Handle construction

Takedown

A takedown is a hidden-tang construction built to come apart. The tang passes through the handle and is drawn up by a threaded fitting — a nut at the butt, or a pommel that screws down — so the handle can be dismantled and re-fitted rather than being permanently bonded in place. Everything else follows the hidden-tang pattern: a concealed tang inside a one-piece handle, with no steel showing along the grip.

The point of the design is serviceability. Because the handle is mechanical rather than glued, it can be taken off for thorough cleaning and drying, swapped for a different material or profile, or replaced entirely if it is ever damaged — all without destroying the original fittings. It is the construction to choose for a knife meant to be maintained and kept for the long term, and for owners who like the option of changing a handle later.

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.
