Tried to post it yesterday, but didn't menaged.
So in the pic, from left to right we have: Iisakki Järvenpää Aito, Pasi Hurttila tuohisarvi, Eräpuu tuohitako, Pasi Hurttila tuohipää.
Iisakki Järvenpää Oy is one of the oldest puukko factory locatd in Kauhava. The founder was royal knifemaker for tzar Nicholas II Romanov for a while and was awarded for his quality job.
Reino Känkänpaa, father of the now retired Altti Känkänpaa, worked for Iisakki for some time before starting his own business.
Aito was on of the craftmen at Järvenpää's factory. He was one of the men working for the longest time and the most skilled.
Eräpuu is a family business, based in Kemi, owned by the Kehusmaa brothers. They sell not only knives but also any sort of lappish souvenirs and clothing.
The knife in object has a Lauri blade with fake hammered finish, so to be similar to the Känkänpaa ones they used to use.
Pasi Hurttila is a full time blacksmith working in Ivalo, 30 km from Lake Inari. He worked for 10 years a wilderness guide all around Lappland before shifting forging from hobby to work.
