I've been collecting and using puukkos and nordic knives since 2003. As many I've started with Marttiinis since they were the only available in Italy at the time. These were a Lynx, a short leuku, a collector version of the Lynx and a rubber handle one.
I wasn't really impressed, though, by the very touristic feeling they had and by the not so great 420 use. At the time, I only felt somehow dissatisfied and couldn't quite get the particular that didn't click with me. I understood the "tourist feeling" some time later, after having bought and used other knives.
So, I moved on from Marttiinis and stepped into Iisakki Järvenpää Oy. I bought and used seven of their knives and got myself busy for a couple of years. I hadn't found yet a preferred style, so I got a couple of their knives with handlocking handles, a horsehead combo and three from the Lappland series. Of these the last three were my favourite since the handles felt better in use and also due to the kind of Sami background.
In the same period I started to get interested in nordic culture and began to self teach me about it with a lot of reading and starting to frequent BritishBlades.
Given my then lower financial possibilities, I kept searching among the various mass produced puukkos, so I bought two Eräpuu and four Kauhavan Puukkopaja. I also got four Paaso puukot, a Wood Jewel and a Ahti Metsä. All nicely made but didn't lit the spark. All these had either a "bird's head" pommel or a slightly flared one.
The first turning point was the encounter with Gransslöjd knives, made by Kimmo Sorvoja in Haparanda. Though still quite mass produced, it was my first experience actually talking to a maker about what I was searching: his ideas, materials, how he worked etc. Thanks to this I also had my first experience with a forged blade, made by Toivo Jaaranen from Pello. Gransslöjd made my benchmark for mass produced nordic knives, since they had the best fit, finish, feel and character of all those I've tried. I got six knives from him, none with a barrel handle.
Though real custom made knives were still out of my budget, I became very aware of them and started to look deeper into them.
In 2008 I got my second turning point, when I started to talk a lot with a BritishBlades member, Swedish hobbystic knifemaker Karl-Erik Lindblad. At the time I hadn't tried yet a proper barrel handled puukko and I thought my preferred style to be a "fishtail" handle, common on Swedish knives.
So, the lot of talk about his works, how he did them, all the pictures he posted on the forum and the additional talking about the two commissions I ended up asking him finally put me into the custom knives world. At the same time on BB happened the huge breakdown of Joonas Kallioniemi. While his puukkos spoke to me by a practical point of view, I couldn't stand his obsession with glossy polishing and quite slim proportions that, to me, took away for the user roots of the knives.
In late 2010 I got my third and biggest turning point, purely by chance. On BritishBlades started to post another Finnish hobbystic maker, Sami Lansipaltta, and one of his knives sported a blade made by Pasi Hurttila. I studied Hurttila's website, saw his knives at the time had fishtail handles, so I decided to drop him a line.
The talks that followed opened me the doors to blacksmiths world. I realised I found not only a maker crafting what I though was my favourite style of knives, but also somebody willing to share and talk freely about his job to a level I hadn't experienced yet, but was searching for. Lindblad at the time didn't make his own blades and Kallioniemi was a bit erratic on replies. When I tried to contact other makers for pure blademaking talk, I never got replies or very generic ones.
Hurttila, on the other hand, was very easy going and down on earth about blacksmithing. This also gave me the possibility to talk about Finnish culture and hiking as well.
So I got two fishtail puukkos from him, one of which with a rhombic blade. That was another huge discovering, that redefined the concept of bite. The last turning point to finally settle my preferences was in summer 2011 when he made me my first birch bark puukko, paired with rhombic section. The simple and humble barrel handle was the reply to my searching, but was so obvious I didn't considered it. How fool of me.
Since then I basically sticked to the barrel handle+rhombic blade configuration, which has become my benchmark. Thanks to Pasi Hurttila I had the possibility to know other smiths that shared their open mind about explaining and talking, in particular Ilkka Seikku and Jani Ryynänen.
In 2013 I started my collaboration with Nordiskaknivar blog and this gave me the idea for the human portrait we've done for many knifemakers and blacksmiths. This allowed me to talk to many other makers, saying Saku Honkilahti, Jukka Hankala, Martti Malinen, Kay Vikström, Pasi Jaakonaho, Mikko Inkeroinen, Antti Mäkinen...
So, as said, my personal preferences go to birch bark, rhombic section puukkos, but my main issue with calling puukko anything remotely similar is that to really understand what a puukko is you have to understand the culture behind it. My feeling is that the word is used more due to the current popularity of the style and his usefulness to identify a certain type of field blade, but without knowing what it really is, somehow lacking respect for it and the Finnish people.
