Puukko's Only


Blade stamp says it's Subtle Forge / Jeremiah Mahoney.
Sheath made by Paige May, his stamp is North Star in the sheath.

Thank you LasseH. I'm liked how blade made ( grind) on this Knife. Alex.
 
one more question. Who can identify these two puukko? They look and are made similarly. But have different stamps. OK and AK. AK is shorter.
That would be Otto Kemppainen and Alpo Kemppainen. Highly regarded puukkoseppa, especially Alpo. I'm not sure how, or if, Otto is related to Alpo.
The OK could also be Olavi Kemppainen, brother of Alpo Kemppainen as I'm not certain if Otto ever used "OK" as his stamp

Paging @Frederick89

Edit: If you get tired of either of those, let me know. I think I could help out!

I usually don't like days like this and I hope they never come. But never say never.
You will be second in line. Thank you.
 
That style matches NOT w Kemppainen bros.
I have both of them in my stamp collection and that does not match.

Besides, stamp is on left side.
That suggests the smith forged only the blade and sold it.
CORRECTION TO PREVIOUS: Found a pic from local auction page selling OLAVI Kemppainen puukko.
Stamp is OK on the left side.
So that is right answer.
LATER DATA: Master Smith Pasi Jaakonaho confirmed my doubts: it is OLAVI Kemppainen.
So for AK I found from italian forum a note... Tommi-puukkos have been made also by ANTTI Kemppainen.
Stamp on visible on right side.

But ask from Otto, he is in the Facenook.

I have seen a handful of similar knives on fleabay in the past. All marked either AK or OK on the left side, same wood handles and forge finish blades. All sold for ~$200-`250. All were sold from eastern Europe / Russia. Hard to say if they were real, I had my doubts.
 
OK - Olavi Kemppainen OK

According to Kainuun, this was original maker of Tommi puukot. Others do not agree.


AK - Altti Kankaanpää, father of Pauli. Altti (mark AK) continued forging puukot until he "retired" at age 85 in 2010. His puukot tend to be shorter in the blade.

AK= Altti Kankaanpää NOT

Here is Altti Kankaanpää-stamp.
Used to stamp also the blades for sale on the right side ( I have two AK-bladed puukkos in my collection; one made by Jukka Hankala, other by Aimo Määttänen.)

To get more info, I threw the ball to Otto Kemppainen.
Asked him about the stamps.

Hi. Who is a maker?
It is Laurent Juhel puukko.

LasseH
That is correct. Laurent Juhel is a maker from France. A few others on here have a maasepän puukko from him. Very simple but functional. I ordered this from the maker and I wasn’t disappointed.

I’m not certain if it qualifies as a true maasepän puukko since it has a full length tang peened at the back. Most maasepän puukot I’ve seen are hidden tang. The puukko cognoscenti may need to opine on that.

Like this Knife. Looks simple but very beautiful. And also high scandi grind makes my heart beating faster.
 
- Natural Resources Institute Finland (Luke) has digitised their 1960 study of Finnish puukko called Puukkojen ryhmäkoetus ("Group testing of puukko"). The institute tested was done between 1957 and 1959. The test measured the hardness of the knife blades in two places on the spine and on the rear, middle and tip of the edge. In addition, the blades were tested for impact resistance and bending resistance, and the whittling properties of the blades, the design of the blades and handles, and the sheath were evaluated. The hardness of the blade is expressed in Rockwell HRC value, except for the three softer blades, where it is expressed in HRB numbers (see the table below). The hardness of the blade edge is expressed in Vickers value and usually in HV30, with one exception, where the hardness is expressed in HV10:

Valmistaja = Manufacturer ("ruotsalaista valmistetta" means "of Swedish manufacture", possibly Mora)
Puukon nimi tai malli = Name or model of puukko
Terän paksuus tyvestä mm = Blade thickness at the base in millimetres
Terän pituus mm = Blade length in millimetres
Pään pituus = Handle length in millimetres
Terän sivun kovuus HRC / HRB = Blade spine hardness in HRC / HRB
Terän suun kovuus HV30 = Blade edge hardness in HV30

1) "Equal to c. 15 HRC value"
2) "Equal to c. 7.5 HRC value"
3) "Equal to c. 10.5 HRC value"
4) "Manufacturer is unknown"
5) "Hardness expressed in HV10 value"

Recent additions to Finnish Siiri database:

- 9th to 11th century puukko drop point blade. The blade length with the missing tip is around 65 mm or about 2.5 inches. Overall length is around 125 mm or 5 inches.

- Replica of 12th century Perniö puukko and sheath made by Finnish Kalevala Koru company in the 1940s or 1950s. The puukko and sheath was dropped out of their catalogue recently and used to cost 1863 € or a bit less than $2200 with VAT.

Hi guys. My first puukko pictures are here.
I also compete in the Finnish knife making and recent years have been great to me. Few years it was a hobby, then I started bladesmith school in 2020, graduated 2023.

These are the places I achieved recently. Below you can see the knives.
If I have to remove leuku and petty, just let me know.

2024 Finnish Knife Association, "user puukko" series. First place. (hamon puukko)
2024 Finnish Knife Association, "Leuku" series. First place.

2025
Finnish Knife Association, "user puukko" winner series. First place. (damascus puukko)
2025 Finnish Knife Association, "Petty knife" winner series. Second place.
omg dude these are beautiful ! anywhere i can check out your work?
 
It is often said that puukkos are difficult to sharpen.

Somehow the Finns were able to do it freehand, with locally available sand stone. I found this well used sample at the local flea market and it is from pre-Carborundum era, maybe 1800s. There is a place some 30 kms away where flour mill grinding stones were made. It´s called Sieravuori, which would translate as "sharpening stone mountain". Most likely this from there.

My advice to any puukko owner is to learn the skill of freehand sharpening. And please do use some cheap puukko for training ;)
 
Words of wisdom..."And please do use some cheap puukko for training."

Better that than fock your Jari Liukko or Tuominen blade while training.

Moro VTT!
