A variably hardened mono steel blade in the honyaki style, this 150mm petty from artisan duo Luke and Danae Scheepers features a beautiful cloud like hamon extending out of the stunning Karelian birch octagonal wa handle.

The blade features a K-tip and a user friendly 37mm blade height at the heel, which works hand in hand with the octagonal tapered handle to provide a lovely working experience. The convex ground blade has been variably hardened at HRC 61+ providing a lovely sharp edge and cutting experience.

The ScheepersBuilt team have outdone themselves with this lovely set of honyaki pettys in black paper micarta and Karelian birch.

Blade type

Petty

ペティ

The Japanese small utility knife — the name comes from the French petit — typically 120 to 150 mm. A petty bridges the gap between a paring knife and a chef's knife: long enough for in-hand work like peeling and trimming, yet precise enough for detailed board tasks such as slicing shallots, segmenting fruit, or breaking down small items where a full-size blade is unwieldy.

Its versatility is the point, and so is its ceiling. A petty is nimble and confidence-inspiring for fine work, but the short blade and light build make it inefficient for high-volume chopping or anything large. Most cooks keep one as the constant companion to a larger knife rather than as a primary.

Cutting edge steel

W1

Plain high-carbon water-hardening tool steel

Typical HRC
62–65
Corrosion class
Carbon
Production
Conventional
Origin
United States (AISI)

W1 is the Western archetypal water-hardening tool steel: roughly 1.0 percent carbon, no meaningful alloying, designed to be quenched in plain water. In its kitchen knife form it overlaps closely with European C105 and Japanese SK3 / SK105, and it is the ancestor of much of the Sheffield clean-carbon tradition.

For the cook it lands at 63–64 HRC in a careful heat treat, sharpens at the level of a Hitachi white paper, and behaves at the apex like the cleanest Western carbon you can buy off the rack. The trade-offs are familiar: minimal edge retention compared to the alloyed carbons, a lively patina, and a heat treat that demands attention to detail because there is nothing in the chemistry to forgive a sloppy quench.

W1 has largely been superseded in production work by W2 and the modern engineered carbons, but it persists in the work of traditionalist American smiths and is occasionally found in revivalist Sheffield production. Among the makers Modern Cooking carries, Jonas Johnsson and ScheepersBuilt work in W1. As a reference steel for "what a pure carbon should feel like," it remains honest and useful.

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

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

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.
