Teeth Don’t Lie: Field Notes on a Rasp Knife named “Bull Cutter”.

There are teeth… and then there are teeth.
Serrations — and rasp.
Let’s get one thing straight.
This is not a “knife made from a rasp.”
This is a farrier rasp that refused to die.
(A farrier takes care of the feet and hooves of equines, whether donkeys, ponies or horses. He takes care of fitting and trimming the shoes.)
And when the knifemaker knows exactly what he’s doing — and here, Robin Medina Thomas from La Coutellerie de la Vallée clearly does — you end up with a blade that doesn’t just cut. It commits. Playfully.
Carrying its inheritance in both form and function.

The blade retains the unmistakable imprint of its former rasp life.
A thick spine, yet a remarkably fine cutting geometry. Along the upper section, the rasp’s triangular teeth remain smoothed — not as ornament, but as a deliberate act of preservation… a generous spine that offers a wide, comfortable track for the thumb.
These elements speak of force.
From abrasion to raw, unapologetic function.
And then, just below, everything shifts — through transformation.
In an age of excess and waste, this feels almost essential.
Not just recycling, but refinement.
A second life in excellence !

Rasp steel is high-carbon steel, typically around 1% carbon.
An old-timer alloy — simple, proven, and unforgiving if mishandled. No modern complexity.
Just steel that responds directly to heat, to grinding, to use.

And when treated right, it delivers exactly what matters:

Edge, bite, and honesty — with a potential remarkable tolerance for abuse.

That’s why this kind of steel has long been favored for expedition and field knives (TOPS, ESEE…). It has proven itself where it matters most: in wood, in weather, in real use.

Not in theory. In the field. You cant go more traditional than this.


Deep, smooth, almost liquid in its reflection, the zebu horn handle creates a striking contrast with the blade’s aggressive texture — a dialogue between softness and bite.
The transition is not only visual. It is tactile. Almost sensual.
Oh, this is a tool made with love, and a companion, still becoming.

And you feel it immediately in the balance and ergonomics.
The fingers and palm find their place naturally — no adjustment, no hesitation, no hot spots.

The spine is just right for controlled push cuts, offering both comfort and precision.
This is, above all, an excellent trimming knife.
It can also find its place in bushcraft.
Easy to bring back to a razor edge, and forgiving in use — a knife that works with you, not against you.

The profile remains restrained.
A compact geometry, balanced, with a gentle curvature that favors control over demonstration. The bevel is generous, inviting engagement without excess resistance.

Used in wood, the blade reveals its true character. It confirms the visual promise: entry is immediate, the cut remains stable, the material yields without fracture.

Under diamond stones, the edge feels stubborn—almost reluctant to yield.
But that resistance is a good thing.
As legendary knifemaker Des Horn once put it: “It’s not easy to grind carbon steel without raising the temperature too high. If it turns blue while grinding, it’s much softer.”
And that Bull Cutter’s rasp steel? It’s properly hard.

As a bonus:
Carbon steel and zebu horn share a common trait: they will change.
The steel will soon take on a patina, marking time and use.
The dark brown horn will slowly deepen, its surface already showing and gaining subtle complexity.
These are not signs of wear. These are the continuation of the object.

And Robin’s Bull Cutter is really a knife made to be enjoyed in the woods. He will see a lot of kitchen times too because the sheepfoot blade is non-threatening, almost reassuring — even to those who don’t speak the language of knives, as they are drawn to the story of a farrier’s rasp given a second life.
The guard locks the hand in place with quiet confidence, and the thin edge invites controlled push cuts with ease.

Robin made this knife for his own enjoyment — and you can feel it.
There is substance here. A certain heft in the hand, just enough to carry momentum when working light branches. It’s not meant for show — it’s meant to be used.
A compact blade with presence.
A small tank, stripped of frills and completely free of tacticool pretension.
Instead, it carries something rarer:

There is an old-timer aura….
The kind of knife that feels familiar the moment you pick it up as if that steel had already lived a looong life before reaching your hand.
It also echoes my long-standing appreciation for Schrade Old Timer fixed blades: the same kind of steel, the same pragmatic lineage.

“Excellent. Those are heat treated for hardness and not strength but are thick enough to be strong enough.” Des Horn.

And then there is the sheath. Modern. Minimal. Black. Functional.
No unnecessary flourish — just a pancake kydex shell, shaped tight to the blade, held by a simple cord system that lets you adapt carry without overthinking it.
Your knife is a tool, destined to be in your pocket, belt or bag, when you go in the woods.
This kind of sheath are indestructible and they dry easy.

The handle can be crafted from a selection of carefully chosen woods and natural materials, each bringing its own character and depth:

  • Curly Birch — light-toned and finely figured, with subtle flame patterns that shift under the light, offering both elegance and warmth.
  • Boxwood — dense and smooth, with a pale golden hue that evokes traditional European craftsmanship and understated refinement.
  • Yew — rich in contrast, blending warm amber tones with darker veins, a wood long associated with heritage and resilience.
  • Yellow Locust (Black Locust) — robust and naturally durable, with a deep, earthy coloration that speaks of strength and longevity.
  • Rosewood — dark, luxurious, and complex, with deep reddish-brown tones and a natural luster that brings a sense of quiet opulence.
  • The list goes on…

For around 100 euros (mine was 110), the Bull Cutter doesn’t belong in a display case. This is Robin’s favorite design and best seller. It belongs in the forest — in valleys of green and grey, following the rivers as they meander through the land.

It is a coup de cœur for me — and my kind of tribute to a young, gifted knifemaker.

In use. This rasp steel was born to remove matter.
It still does in a new sharp shape.

Pekka Tuominen – The Master of the Boreal Blade


It was upon receiving one of my friend Jur’s knives — a superb hunting knife by Pekka Tuominen dating from 2012, forged in Silversteel and fitted with a handle incorporating walrus ivory — that I felt compelled to turn my attention back to Pekka Tuominen.

People often ask me: who is Pekka?

Consider this, then, a renewed portrait.
Because in Finland, a knife is never just a knife.

And the snow is never just the snow.

In the deep boreal forests where autumn means moose season and winter hardens the earth into something resembling iron, blades are not judged under showroom lights but against bone, sinew, cold, and time. It is in this demanding landscape that Pekka Tuominen has built his reputation — quietly, methodically, without spectacle.

He is not a factory. He is not a brand machine inflated by marketing departments and limited drops. He is a craftsman in the most literal sense of the word. And among serious Nordic hunters, his name circulates with a particular, understated respect.
Pekka’s relationship with knives began before memory. His grandfather, a part-time blacksmith, forged blades; his father worked as a carpenter. He received his first knife before the age of five. For him, the object was never exotic — it was elemental.


As a teenager immersed in scouting and outdoor life, he reached a simple conclusion about survival: the most important tool in the wilderness is a knife. Naturally, in Finland, that meant a puukko. At eighteen, he studied in Inari, in northern Lapland, training as a wilderness guide. There, he learned the fundamentals of puukko making. That period marked the true beginning of his craft.
A decisive intellectual influence came earlier, when he first read Sakari Palsi’s 1955 book Puukko. The text, he recalls, opened his eyes. It clarified what truly defines a puukko — not ornament, not material excess, but proportion and line.
For Pekka, a knife unites tool, design, and art in a single object. He cannot imagine life without one.
I have written a long review here about it.

Ask him to describe his ideal puukko — as a user rather than a maker — and he returns to simplicity. A blade of approximately 90 millimeters, paired with a 110 millimeter handle. Dimensions rooted in tradition, refined by use. Multipurpose, balanced, restrained.

He appreciates steels such as 115CrV3, often referred to as Silversteel, RWL34, and 52100. Yet he insists on a hierarchy that reveals the seriousness of his approach: the steel matters, but heat treatment matters more.

He is no rigid purist. One of his own heavily used test knives pairs stabilized black ash burl with a CPM S30V blade. He admits to having “wrongly” used it — and to grinding it down repeatedly as a result. For Tuominen, a knife that remains pristine has not yet fulfilled its purpose.

In an age of aggressive silhouettes and theatrical grinds, Tuominen defends restraint. A true puukko is defined by a relatively short, straightforward blade; a handle without finger guards; no exaggerated pommel; and clean, continuous lines that flow from tip to sheath.

He favors birch bark for its warmth and grip, but also works with curly birch and Micarta. His sheaths are hand-stitched, typically from vegetable-tanned leather. He admires traditional Finnish patterns — Tommi, Pekanpää, Kokemäen — whose differences lie more in decoration than in structure. The essential design language remains consistent across regions.

“The material does not make a puukko,” he says. “The design does.”

In Finland, the word puukkoseppä carries weight. It does not describe someone who merely grinds blades. It denotes a professional who forges, heat treats, shapes, finishes, and sews — who understands the knife as a complete entity.

Tuominen forges Silversteel and 52100, as well as his own Damascus from 15N20 and 1090. Stainless steels such as RWL34 are ground rather than forged. In every case, he performs the heat treatment himself.

This decision is not romanticism. It is control.

Heat treatment determines hardness, toughness, edge retention, resistance to chipping, sharpening behavior — in short, character. By managing austenitizing temperatures, quench timing, temper cycles, and when appropriate cryogenic steps, he tunes each blade for hunting reality rather than laboratory extremity. He does not chase maximum HRC for marketing appeal. He pursues balance.

The difference is felt not in specifications but in seasons.

One Finnish hunter wrote on a forum, after two moose seasons with his knife, that he had done nothing more than strop it. A Swedish outdoorsman described the sharpening behavior as clean and predictable, “no surprises.” The praise is never flamboyant. It is consistent. Stability, reliability, endurance.

While many outside Scandinavia associate Finnish craft primarily with the puukko, Tuominen’s strongest following among experienced outdoorsmen is tied to his dedicated hunting knives. These are not nostalgic reinterpretations of folklore. They are instruments designed for skinning and field dressing large game in cold climates.

Their geometry avoids ego. Clean drop points, disciplined grinds, carefully judged balance. No theatrical belly, no tactical posturing. In hand, they feel neutral — and that neutrality becomes invaluable during extended work. Fatigue diminishes. Control increases.

In sub-zero conditions, poorly treated steel reveals itself quickly. Edges chip, roll, or turn brittle. Tuominen’s blades are repeatedly described as stable. It is a modest word, but in the field it is decisive.

Finland formalizes its craft traditions through national qualifications overseen by the Ministry of Education. Tuominen earned the title puukkoseppämestari, Master Blade Smith, after passing rigorous examinations and presenting a master’s work to a jury. At the time of his certification, only seven craftsmen in the country held that distinction.

Today, knife making occupies the vast majority of his time. His waiting list extends roughly a year. Collaborations, including work with Spyderco, have broadened his international presence. Yet when asked about ambition, his answer remains almost disarmingly modest: he wants to become a better knife maker.

He considers craftsmanship a lifelong education — one in which imperfections are not failures but invitations to improve.

In a global knife culture increasingly captivated by spectacle, Pekka Tuominen’s work stands apart for its restraint. He works alone. He grinds, heat treats, shapes, and stitches himself. From blade to sheath, the knife remains under one set of hands.

He often summarizes his philosophy with a line that sounds simple enough: a simple man makes simple knives.

In Finland, however, simplicity is never simplistic. It is discipline. It is proportion. It is respect for the task at hand.

And in the forest, that is what endures.
