From above:
"PURMO was founded in 1953 in the Finnish town of Purmo, near Jacobstad by three entrepreneurs. It
initially began as a bow saw manufacturer but in 1956 relocated to Jacobstad and expanded into garden furniture, snow clearing equipment and
farming tools. At the end of the 1950s the PURMO brand was well established and the company bought a small radiator manufacturer in the area called Terjårv Wårme. The PURMO radiator soon became a market leader and, in the 70s, was bought by the Rettig Group.
The company’s name was changed to Rettig Vårme and the factory moved to Peders in Jacobstad, where it is still based today, producing 900,000 units each year."

farming tools" presumably including axes?
Rettig Vårme:

"The company's first product was Purmosågen - a bow saw that had a striking approach. The predecessor had a bow made of wood, but Purmosågen was made of metal"
