The "Fathachspás" is a 190mm cleaver forged by Erik Gullikson, featuring his bold and iconic "Tiubh" design with sweeping lines along the spine and angular, versatile profile. Its name "Fathachspás", meaning "space giant" in Irish, reflects its bold dimensions and functional, high performance design. Crafted from ApexUltra steel, known for its exceptional toughness and edge retention, the cleaver easily handles heavy workloads. The blade’s broad profile and weight make it ideal for cutting large root vegetables, while its sharp edge ensures precise, clean slices.

The blade features an "S grind," a specialized compound geometry that offers superior cutting efficiency and reduces friction during slicing. With an overall length of 295mm and an edge length of 190mm, it excels in handling demanding cutting tasks.

The handle of the Fathachspás is a hidden tang construction made from lightweight aluminum, complemented by an heirloom-fit geometrical bolster crafted from darkened zirconium. The aluminum handle mirrors the blade's crater-like texture, giving the cleaver a cohesive, otherworldly aesthetic that lives up to its name. Designed for ambidextrous use, the handle provides a comfortable grip for both left and right-handed users.

A masterful design by Irish craftsman Erik Gullikson, this cleaver not only delivers exceptional performance and user satisfaction in the kitchen but also stands out as a striking statement piece, blending functionality with aesthetic appeal.

Blade type

Cleaver

A broad, heavy, rectangular blade — and a term that covers two very different tools. The heavy Western butcher's cleaver is built with a thick spine and robust edge to chop through bone and joints; the lighter Chinese vegetable cleaver (càidāo) has a tall, thin blade that is a surprisingly nimble all-purpose knife, with a wide face useful for scooping. Knowing which one is meant matters.

A true butcher's cleaver trades all finesse for the mass and durability needed to split bone, and it has little place in delicate work. The Chinese vegetable version is far more versatile than its size suggests but is not built for bone at all, despite the shared silhouette. The shape promises power; the specific knife determines whether that power comes with any subtlety.

Cutting edge steel

Apex Ultra

Low-alloy fine-grain carbon tool steel

Typical HRC

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

Mono Steel

A knife forged from a single piece of steel — no laminations, no clad layers. The simplest and most direct construction. The entire blade is the cutting steel, with no softer outer jacket to protect or contrast it. Most contemporary Western kitchen knives in carbon and stainless steel are mono-steel constructions, as are honyaki and most European bladesmith work.

The trade-off is straightforward: mono-steel knives are easier to forge, sharpen, and reason about, but the entire blade carries the cutting steel's properties — including its reactivity if it's a clean carbon. There is no soft jacket to protect a more brittle core from impact, so the heat treatment and geometry have to do all the work.

Grind

Compound Grind

A category covering blades ground with more than one geometry stacked into a single cross-section — typically a convex (or flat) primary bevel at the very edge, with one or more hollows ground higher up the blade face to relieve material behind it. The aim is food release and reduced wedging: the hollow opens an air gap so dense produce breaks away from the blade instead of clinging to it, while the convex steel at the edge keeps the apex strong and the knife driving through the cut.

The named variations in the Modern Cooking catalogue differ in where the hollows sit, how many there are, and whether the two faces are ground alike:

S-Grind — a convex primary bevel at the edge with a hollow ground into both faces just above it. The symmetrical "S"-shaped cross-section is the classic food-release grind: relief above the edge, strength at the edge.

C-Grind — an asymmetric S-grind. Both faces keep the convex primary bevel, but only one face carries the hollow above it. The single-sided relief biases food release to one side, and is simpler to grind and to maintain than a full S.

B-Grind — a stacked twin-hollow grind: a tight, narrow hollow immediately above the edge, with a second, broader and wider hollow above that. The staged relief gives especially strong food release across the height of the blade.

S-Hook Grind — also called a hook, harpoon, or J grind. An S-grind taken to an extreme, with the hollow placed very close to the cutting edge. The aggressive near-edge relief gives outstanding food release, at the price of being the most maintenance-sensitive of the family.

Asymmetrical-B Grind — a B-grind in which the twin-hollow structure is carried on one face while the other is ground differently (or left without the upper hollow), off-setting the edge. It combines the staged food release of a B-grind with the handed, steering character of an asymmetric grind.

In every case the gain is food release and reduced drag, and the shared cost is sharpening: as the edge is thinned over the knife's life, maintenance eventually reaches the hollowed steel, which cannot be flattened on a stone the way a convex or flat bevel can. How soon that happens depends on how deeply the hollows are cut and how close to the edge they sit — exactly what separates a gentle S-grind from an aggressive S-hook. These are high-craft geometries, prized by makers and experienced users for their cutting feel, and best appreciated by a cook who maintains their own edges.

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.
