Mora Knife

By Federico Buldrini

Morakniv AB has its factory in Östnor, 6 km from the town of Mora, capital of its municipality, in the county of Dalarna, central Sweden. From Dalarna county comes one of the symbols of Sweden, the Dala horse, produced at least since the 17th century, but probably much older, while the massive production of knives in this region dates back to the 18th century, however following typical characteristics of the medieval brukskniv.

In 1891 Frost-Erik Ernström began producing knives to use in his timber sleds factory, but soon expanded production and ended up fully converting the factory to the production of cutting tools. Erik Frost AB was born. In 1912, after being thrown out, literally, from the Ernström factory, a young worker, Krang-Johan Eriksson, founded a competing factory with business partner Lok-Anders Mattsson. KJ Eriksson AB was born. Until 1956 the sheaths for all the manufacturers were crafted by the shoemaker Ström. He was also the first to experiment sheath making with the “Unica” vulcanized fiber, that would eventually replace leather.

Frost AB expansion allowed the birth of several other small companies, often founded by former workers. These small businesses frequently bought raw materials from Frost and then built their own knives. In the 60’s Frost and Eriksson, always remained the two largest companies, began to buy out almost all the other small firms unable to withstand the fierce competition to which they were subjected, thus ensuring themselves an almost complete monopoly. In 2005 Eriksson concluded the acquisition of Frost, a process that began with the sale of part of the shares owned by few members already in 1988. Mora of Sweden AB was born. During the settling period and the gradual shift of all the production in the Eriksson factory there was a noticeable decline in quality control. In 2016 Mora of Sweden changed the name to Morakniv AB.

The model that I review is the Classic Original 1, the first incarnation of the “Mora” knife as we know it today. Unlike the more popular, common and cheap models it has kept the main features of the brukskniv from which everything started: laminated blade and uncolored handle. The sheath is made of vulcanized fiber. There is also the “Exclusive” variant with a leather sheath. The red color of the handle was introduced in the 20s, in various shades, as an imitation of mahogany.

After the war, due to the shortage of leather, started the massive production of vulcanized fiber sheaths, which had already been slowly replacing the leather ones since the 20s. In the 50s it began on the other hand the increasing use of plastics for both handles and sheaths and this was, ultimately, one of the key factors that allowed Frost and Eriksson to take over the monopoly.   The laminated steel is currently used only in the Original Classic models and for the carving knives. I attempted to investigate the steel used, but the best I could get was a confirmation that the core is in O1 from Western Europe, surrounded by sides of a low-alloyed steel, produced by the same factory, containing less than 0.4% C so as not to interfere with O1 heat treatment. For writing convenience I will define it 1035.

Technical data


length       99 mm

width       18 mm, thickness  2.5 mm

tang        2×3 mm at pommel

steel         O1 core, 1035 sides

bevels       flat edge 28°

hardness   ~ 59 HRC


length         102 mm

width         24 mm max. thickness     19 mm max.


knife           60 g, with sheath 80 g


The flat section blade is stamped from a laminated steel bar made of a O1 core, surrounded by 1035 sides. It is untapered both in height and thickness. The bevels are flat, with a 28° edge taken to zero. Out of the box it was shaving sharp. The tang is secured with a tubular rivet. The common birch handle is machine-made, then assembled and riveted by a worker, without the addition of epoxy. It is sanded with a medium grit and tapers in both directions. It fills well the hand, but is very slender and thin. It has a marked oval section and a good junction between blade and ferrule. The 1.5 mm thick vulcanized fiber sheath is sewn on the back as its leather cousins would be. It has a slotted leather strip, originally designed to carry the knife hanging from a special button, once present on work clothes. Now it can be exploited for neck carry. The sheath, unlike the plastic ones of the red handled Classic models, holds the knife well. In use The knife comes directly from the factory, but both the ferrule and the iron fixing the leather slot were rusted, so I cleaned them with steel wool.

The blade was shaving sharp, but the junction between the flat and the curve part of the edge wasn’t perfectly smooth and didn’t shave. Extremely light, it weighs with the sheath as the Basic 546 alone. The blade spine is rounded for better comfort when applying pressure with the thumb or fingers of the weak hand, depending from the cuts. The junction between bevels and cheeks is rounded as well to reduce friction during cuts.

During the elderberry spikkentroll carving it had good bite, for a flat section blade, but the wood curls were a bit less precise and tight than those possible with rhombic blades.

Since the edge has a really flat portion, rather than a slight continuous curve, I felt this as a drawback on biting potential. This, together with the knife little mass, make it suffer a little during roughing carving and stop cuts. At the end of the work the edge was pristine.

Later I carved a silver fir spatula. The first thing that struck me during the roughing cuts, far bigger than those necessary for a spikkentroll, was the feeling of smallness of the handle. Then I noticed a very quick tiring in my arm due to those minute proportions of the handle, no matter if I did push cuts with the knife or pulled the wood against the blade with my weak arm. The rounded spine was good enough for the thumb of the weak hand during refining push cuts, but it can still be a bit painful if much pressure is applied.

No problem in finishing cuts, where the knife transformed into a very agile and biting little thing. At the end of the work it was still shaving, but had lost some bite and gained two microchips on the flat portion of the edge.

Being accustomed to essentially using custom made rhombic puukkos I realize that I have a very high benchmark, so my judgment is to be taken considering my excessive pickiness, which doesn’t spare puukkos either.

To me the Mora Classic Original, as currently produced, has shown great potential for working both on green and seasoned wood. However, on seasoned wood, what it gains thanks to its geometry, it is largely lost due to the general lack of mass and, especially, the really small proportions of the handle.

The blade has a good combination of thin stock and not too acute bevels, which allow a good compromise of bite and resilience, actually slightly better than that of the #106 carving model.

The handle is the major flaw. Its proportions make it small even for those with medium-sized hands and are far too insufficient for roughing cuts on seasoned wood, even for a smallish project like a spatula. A handle with the same proportions of the aforementioned # 106 (108x29x22 mm), would make a totally different knife.

To sum it up, the knife has good performance on green wood, on very small projects on seasoned wood and is fair enough for basic bushcraft use, but pays way too much its handle proportions for anything that is more challenging.

Seishi Oizumi; Bush n’ Blade

Seishi Oizumi:

For a long time I thought I was the first one in my family to become a knife maker or any kind of professional crafter. Recently I have discovered that my great grand father on my mother’s side was blacksmith in Finland, so I do have maaseppä in my background and perhaps, that blood drew me in to this profession. However, I enjoy knife making very much and I am thinking about it 24-7.

I am interested in making things with my hands and have no fear of DIY so, I started as self-taught and that went on for quite a long time. I only started to become interested in getting a teacher when I realized that I wanted to do this professionally. It was also about the same time I was reaching the limit of being self-taught, especially in the area of traditional puukko making. Luckily, Mr. Taisto Kuortti was teaching traditional puukko making nearby, so I started to take his courses for his teaching.

Knife making tradition… I am not sure, but tradition of living with blades, YES.
Those of you who know me probably know that I am Japanese. Born in Japan and grew up in Japan. But not many know that I have a Finnish mother. I grew up hearing and seeing about Finland and its culture through her.
When I was child I was naturally surrounded by Japanese bladed tools and a culture where the blade has special value and role. Raised with how to respect the blades, not just because it is an important tool or could be dangerous, but because it is a tool that has soul.
Well… it does sounds cheesy and too dramatic to say so, but that was how the elderly generation around me treated the blades and that is how Japanese blade smiths are creating blades.
As for the Finnish traditional blades, my first fixed knife was Finnish puukko. I was interested  how the knife was carried and used daily in Finnish old days. Hearing my Finnish grand father’s stories and so on, I remember fantasizing myself back there and carried around knife in my local woods to make use out of it even it actually did not needed.
My biggest source of  inspiration is traditional Japanese and Finnish crafts.
When I get inspiration, I try not to just copy the look, it is important for me to learn its back ground as much as I can. The history, the culture, how it is done, the tools used etc. and often that background gives me a much more wide range of inspiration.
IWG model for example
It was inspired by Japanese indigenous Ainu peoples’ knife. The original one is called Makiri. When I saw it, I started to think how to bring it in to Finnish style knife. As I researched, I started to see the similarity in saame style knife in its look, use and culture.
From that IWG leuku was borne. Since then I have been making different versions of this knife and the latest one in the picture received first place in modern puukko at SM puukko kisa this year.
I am not much of fashion person, but think would be so cool to have a knife hanging that tells others who you are.  In city life, people dress up, wearing all kinds of accessories to make oneself unique. Decorate oneself how you want to look. So I started to make knives because I wanted the knife that does the needed job in the woods and does look nice.
If you think of knife as just a tool, then perhaps a wild looking straight out of the forge blade with what ever works on the handle does the job. (do not take this wrong way, I am not criticizing that. in fact, I love those style and I do make them as well) But if you look back at the history of knives, the user/maker has been decorating the tool blades in some way and it had some meaning to the user.
The bottom line is a knife is a tool and it must do the job. But at a same time, it is not just a tool to get the job done. It also should have meaning, culture, history, character… and I think that makes a knife interesting. If/when I manage to create a knife that says that to some one, then I could say I have accomplished something.
It is difficult for me to separate hobbies and work because in a way, my hobby/passion got out of hand and it became my profession. Other than knife making, I am also a wilderness and nature guide, so again not completely a hobby but I love spending time in the woods. Taking nature photos has been of interest and a hobby since I was child. One of my new areas of interest is birds. It is such a easily seen wild life yet easily missed if not paying attention.
Here are some of my works. Many are puukko based models but I think there is always some taste of Japanese in it. My good friend named my style “Scandiasian”. I think the name describes it well of my work and myself.

YP-Taonta Review by Federico Buldrini

YP-Taonta is a small company, founded by the old master Yrjö Puronvarsi, located just outside Härmä, a town 24 km south of Kauhava. Since 2006, the torch has been passed to his grandson, Antti Mäkinen, who continues the family tradition, keeping both his grandfather’s punch and style, while adding a few personal touches. Yrjö, however, continues to forge every day as a hobby, in spite of being 88 years old. Most of the production is focused on iron objects and on blade forging. See this post for more information on YP-Taonta:  yrjo-puronvarsi-blades-yp-taonta


Yrjö Puronvarsi and his grandson Antti Mäkinen at work at YP-Taonta



Technical data

length         106 mm
width           20 mm
thickness     4 mm at the spine; 5 mm where bevels start
tang             3×3 mm at the pommel
steel             C75
grind           concave
edge angle   21 °, tiny convex microbevel
hardness     ~ 60 HRC at the edge

length         120 mm width           29 mm max. thickness     20 mm max.

knife             100 g with sheath   150 g





The blade is forged from C75, European equivalent to 1075. It was first roughed out with power hammer, then finished with hand held hammer. It has a rhombic section slightly tapered in height. After annealing and normalization it was heated on the forge, quenched in oil and tempered in an electric oven. It came shaving sharp. The common birch handle was machine roughed out and then finished on belt sander. It is sanded with a medium grit; it’s slightly tapered towards the blade in both height and thickness. It fills well the hand and has an oval section. The collar and brass rivets are made by Lauri Metalli Oy. The 2 mm thick leather sheath, is made by the Kari Rämäkkö factory, which also supplies several other Finnish companies that produce knives on a large scale. Machine sewed, it has a simple plastic liner inside. The belt loop is the usual twisted strip of leather. To improve retention a small leather strip was added in the inside of the mouth.

In use

When the knife arrived the first 3 mm of the blade’s heel were chipped out, forming a clear half moon shape. This probably happened when hammering the handle onto the blade. So I completely resharpened the puukko with DMT #600, #1200, #8000 and stropped with BRKT black and green compound. The steel proved quick to sharpen and the chip is now reduced.

Now a couple of tests to sum up my impressions.

Firstly I carved a small gnome, in the style of Norwegian spikkentrolls, from a seasoned maple twig. During the carving I felt some resistance from the wood when doing roughing power cuts: the concave bevels bite deep, but have little mass behind the edge to separate the fibers. While performing refining cuts, pulling the puukko towards myself, holding the blade there were no problem and I was able to get tiny curly spirals of wood.

At the end of the work all the edge was still shaving, though it had lost some bite.

After some time, so to avoid enhancing eventual fatigue and without touching up the blade, I carved a butter paddle from seasoned silver fir.

As for the gnome I felt some resistance during roughing push cuts. Also, I was gripping the knife very close to the blade and I had my nails clearly digging in the palm, due to the tapered handle.

During refining cuts, especially in the concave joint between the handle and paddle, the puukko was quite precise, though I felt like the point was slightly too big for the purpose.

At the end of the work I detected three minor rollings in the straight portion of the edge and only the last curved third was still enough sharp to shave hair.


It is not the most precise wood carver, due to its geometry and to the untapered tip, but fair enough for general use.

The handle of this particular model can be a little too slim when grasped near the blade, if working a lot with power cuts or for those with larger hands.

The steel is quite resilient and rolls rather than chip. It doesn’t have a ludricrously long edge holding, but sharpens quick and easy.

A good option for those interested in trying rhombic section puukkos, without going custom right away.




Lauri Karjunen

My name is Lauri Karjunen. I’m 34 years old and I’m from Joensuu, in North Karelia region. Today I live in Hamina, a city in Kymenlaakso region, with my wife and son. I work in the Finnish coast guard, so I’m not really a professional bladesmith.


Lauri Karjunen

On my father’s side, my great-uncle was a professional blacksmith in village Ii, about 35km north of Oulu. I believe he has been the only professional smith in the “close history” of my family.

On the other hand, the old puukkos shown below were made very close to my mother’s homeplace, near Koli, a village in North Karelia, by my grand mother’s cousin’s husband’s father.

I have always been interested in Puukkos. My first memories about them is at a very young age when I was learning whittling with my dad. The puukko has always been part of my hobbies, hunting, fishing and so on. My first puukos were Marttiini and Iisakki Järvenpää factory made ones and they worked well enough. It was 2008 when I decided to order my first custom puukko from bladesmith Mikko Inkeroinen, a Tommi. It was and still is a very good utility puukko, but I was very impressed also of how beautiful it was. Materials, lines and sheath were totally different compared to my older puukkos. I remember that I was thinking how great would have been to have that kind of craftsman skills. I would say that I am half selftaught, but I’ve been lucky enough not to learn everything the hard way. In the beginning there have been few older guys who taught me some basic techniques for forging and heat treatments. If I have to name one, it would be bladesmith Tapani Eskola. But learning takes a lot of time and plenty of repeats to get good results. Internet is also very helpful in these days.

My favorite puukko model is the Tommi puukko. I like to use the same kind of lines in my works too. Rautalamminpuukko is the most beautiful and Kokemäenpuukko is the most fun to make. Sami knives are also something I would like to learn more about.

I get my inspiration from nature and my other hobbies. If I wouldn´t hunt or be interested in the outdoors, I would never have started knife making: I see that these activities are strongly linked to each other. If I would make knies for money, I think I couldn’t enjoy it in the same way. I don´t have any special goal as a knife maker, I just want to improve my skills as a bladesmith. There is a lot of techniques that I would like to learn. Maybe in the future I will do also some different styles of knives.

In Kymenlaakso region where I live there isn’t a particular historical puukko model which is widely known, but at the present time puukko culture is strong and there are lots of hobbyist makers here.

There isn’t any particular known puukko model also in Northern Karelia region where I am from; if I have to name a model as Northern Karelia “maakuntapuukko”, it would be “Karjalan kaiku” puukko from Ilomantsi. It was originally made by Lauri Huurre in -50 (not sure about that year). After him, his son Mauri continued making this model. They are now both passed away but Urpo Parviainen has kept making that model in Ilomantsi.

My other hobbies are, as I earlier mentioned, hunting and generally the outdoors. Being in the forest or near a bog in an autumn morning is absolutely one of my favorite things. Easily better than knife making.

Right now most of my spare time is spent at our home or cabin with my wife and 6 month old son.

Juha Nikki: Recent Work

Juha Nikki – Recent Work

Mike has generously prompted and prodded me for an update on what I’ve been working on recently, so here goes. The knives below have been made in the last couple of years. As you can probably work out, I only make a handful of knives a year.

The latest development for me is that I’ve moved down from Northern Finland –  Lapland – to the South. Whilst here, I’ve been taught to forge my own blades – something that was a surprisingly easy skill to pick up under good tutorship. Which is not to say I’m suddenly an expert smith or even a smith at all, far from it. I don’t think that I’ll make a habit of forging my own blades. I’ll leave that to the smiths who enjoy it – forging was fun, but I like the other aspects of knife making more. There are plenty of good smiths in Finland I can buy blades from. A lot of them will sell blades despite the fact that we have this weird perception here, where everyone who can forge should apparently make the whole puukko themselves and those who can’t (won’t) should stick to knitting. I don’t quite see the reasoning behind it, but people are entitled to their opinions. I might just knit my next puukko handle…

The little knife above is one which I made years ago for my personal workshop knife – it took about 30 minutes to put a handle to and finish. The blade it by a smith in Wales, called Nic Westermann, and it is a little miracle. If memory recalls, it’s about 2 mm thick and 50 mm long. It’s a laminated blade, with a hard core and flexible cheeks. It was as sharp as a razor, very easy to sharpen and kept it’s edge well. It was so good, I regret that it left my workshop… A reindeer herder in Lapland saw it and decided it would be ideal for ear marking reindeer, to I spruced the knife up a bit and made a sheath and regrettably sold it.

The puukko above is in a kind of Sami style and has a blade by Jukka Hankala – I was very lucky to get it through a contact in France, no less… The timber is birch burl from my (ex) local Lappish forest and there is reindeer antler in the knife and sheath, too. The joints in the handle are spaced with vulcanized fiber. I like to file grooves in the joints between different natural materials, as they are bound to expand and contract in different ways as time goes by. The groove will hopefully prevent any obvious notches or steps appearing at those joints. It’s a small job to do and easy to skip, but i like to think details matter. A matter of personal taste, of course – in other places I like rustic finishes.

This knife has a Damasteel blade by Ralph Etzold. The puukko was shipped to Hawaii, which is why the sheath has in its decorations the leaf of both the Hawaiian and Finnish national trees. The handle is stabilized timber and the sheath is of stitchless variety, as most of mine are these days.

 This one was an excercise in design, as the brief from the customer was to make something unusual. The blade is a special commission from Joonas Kallioniemi (again, I was lucky to get such a good and rare blade). The handle is reindeer antler and double dyed Arctic birch burl.

 A skinner knife with a Polar stainless steel blade. Tried a bit of more accurate dyeing on the sheath and made an insert of reindeer antler, which is visible through the holes in the sheath.

A puukko with YP Taonta (Puronvarsi / Antti Mäkinen) blade. A stabilized alder handle, with stabilized materials I usually don’t file grooves to the joints as the material is, well… stable!

YP Taonta blade, ash burl and reindeer antler handle – this time with a groove on the vulcanized fibre spacer. Another stitchless sheath.

A stainless blade by Ralph Etzold, reindeer bolster. The timber is highly figured Arctic birch double dyed. Stitchless sheath.

This blue puukko is a very special one for a good friend. There are several connections to Lapland. It has a Damasteel blade made in Lapland by Ralph Etzold. The handle has a real gold nugget panned from a Lappish river, and the sheath has an Amethyst dug with my own hands from a mine in Lapland.

 Above a couple of photos from my first forging session on a knife making course.

And finally, above is the first complete knife with a blade forged by myself. The metal parts still need polishing, but it’s more or less there.

Note: Please see the Index page for other articles by Juha Nikki, including how to make a stitchless sheath.
