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.

Pekka Tuominen’s Puukko —Terävä Marvel

At the FICX 2019 I have bought one of Pekka Tuominen’s Puukko to replace my Spyderco Puukko.

The husband of Pekka’cousin, who was also exposing as the Paris Knives Show told me: in my country, to “taste” a knife we just hold it in our hand without to loot at it: to feel its balance and if it suits us.
Holding that marvel of a Puukko in your hand is something to experiment. First, the handle is made of birch’s bark, which feels like a hard cork from a seasoned wine bottle. It is soft under the thumb but also grippy in the palm.
Pekka assured me this kind of handle are indestructible! Just some soap and water.
This handmade knife is a display of the highest craftmanship. Everything is perfect.
With that kind of handle, you need a pommel.

As you can see the mirror finish on the nicorros pommel is “melting” with the showing tang’s end. Look closer, there is some microscopic lines ! This is the level of craftmanship you are encountering with Pekka’s knives.

Now the blade being made of RWL34 and mirror finished, it is not easy to picture it without reflections.

RWL34 has been used in the Lil’Nilakka I have reviewed here.
Pekka used his own Spyderco version to cut leather for his sheaths. But I have also seen a video where he use the same puukko as mine in his workshop.
For record, RWL34 is some kind of powder steel version of ATS34: with a very very fine grain and an easy to put a mirror finish on.

A puukko is not a real puukko without its sheath.
I remember 4 years ago, Pekka talking with Sal Glesser about the sheath of the Spyderco Puukko version. There were testing prototypes of the sheath and Pekka was adamant in what retention he was asking from it. It a sheath with wood inlays inside encapsulating the blade, the traditionnal puukko scabbard is very elaborated.

So here are my main Pekka creation, the Nilakka which is my sharpest Spyderco ever.
“Ned” which is a “Urban Hunter II” with carbon fiber and titanium and the new Marvel.

You can notice the pure and clean lines of their edges.

Pictures wise, I will meet Pascal who has bought a Hunter with the same finish as my Puukko. Those marvels encounter will be photographed.

Having harvest a piece of chestnut wood, dried under the summer sun, I have put the new Puukko at the test.

The rounded spine makes it an ideal thumb pushcutting’s friend. The blade goes deep like in butter. In fact it beats the Nilakka and the Hunter in terms of spine confort and for an unknown reason it was just cutting like the proverbial lightsaber. The experience is putting a grin on my face.

To get the blade to the razor sharpness I really wanted , I have used white ceramics for 20 minutes and then leather stropping for another 15 minutes as Pekka has advised.

Yes it is now a razor with the same caress found on the AEB-L Urban.

Now, I’m going to use it also in the kitchen, which is some kind of battlefield where the Puukko will ne

Spyderco Lil’Nilakka – My Romantic Gentleman Puukko.

26234312_10213159758203104_187023894_n

When I consider a new knife, I like to choose it in such a way that it conveys values that appeal to me; in synch with my mood with what I recognize as exemplifying a tradition, a nation; when craft turns into art.

26135013_10213159759163128_1260224319_n

I also opt for features complimentary to the ones I already have so that each knife stands out as champion in its category. Ie this one does not rust, this one will not be taken away from me in UK or Denmark, this one is really good for heavy duty stuff, this one has something so obscene about it I can’t resist!

Setting the mood: read Henrik Ibsen’s Peer Gynt; listen to Symphony n.5 by Jean Sibelius (pictured): dears belling in a barren wilderness where primitive elements collide – wind, sheer stones and icebergs…

…envision cold tundra landscape depicted by Akseli Gallen-Kallela’s paintings – the hard conditions forging men and women. Suomi.

 

A gentleman folder with no pair equal.

Which Spyderco better conveys rigour and austerity of the North other than the Pekka Tuominen designed Lil Nilakka Puukko? It stands out immediately recognizable with its character unlike any other and its craftman, alike the aforementioned finnish artists, is a true representative of the Nordic tradition and nation.

So to summarize: as Sibelius was once said to be the “Chopin of the north”; Pekka the Sibelius of blacksmith and cutlery.

So what is so fantastic about Lil Nilakka?

Still life:

  • Matter of taste: traditional finnish Puukko – I love it!
  • White G-10 so elegant – like ivory but walrus friendly.
  • RWL 34 the Robert W Loveless “in memoriam” steel with excellent combination of corrosion resistance, edge sharpness and hardenability. Also its said to be easy to maintain; good for me!
  • Solid clip that nests Lil Nilakka deep in the pocket

In motion:

  • The Lil Nilakka is snug close-fitting in hand; the forefinger in the G-10 handle opening and the thumb comfortable on the spine thanks to the chanfer.
  • So perfect control when cutting – should that be the x-mas tree branches in excess or the ultimate test: pealing a ripe pear and skinning it angstrom style. The point of the blade and the blade’s width also contribute to making this tool one of extreme precision.
  • Easy to action linerlock and the blade fits perfectly; great engineering work!

 

Mine is #589; with me to stay as my gentleman Puukko!

Spyderco Lil Nilakka Edge rolling out fixed and used.

On my Lil Nilakka You can see the damage on the edge. Dry bambu cutting…

It looks spectacular but it’s just a matter to realign the edge.

It hurst on a new knife !!… Ouch !


In fact I also use diamond to remove some material.


15 minutes later, it is back for more.

Simple tools…

30 minutes later on leather;
Convexing gives a little more material behind the edge. No more stability issues.
And it’s not giving up on performances.
