It was made by Hackman Oy knife company. They are/were a widely respected knife factory, famous for a few knives, yours included. I believe they may of shut down a few years ago.
Hackman is a part of the
Iittala Group. Kitchen and dining cutlery alongside with cookware are still made under the Hackman brand.
The butterfly knife with red nylon handles mentioned by mr. Linton is still manufactured today by a company called Pertemet Oy. They are available here in Finland for 12-13 euros.
The Wirkkala puukko is a beautiful piece, sure enough. But they have very hard blades and get chipped easily. Even
very light chopping or limbing can cause damage. I have seen a Wirkkala puukko take pretty bad damage in a situation where a three and a half euro supermarket puukko would have performed. Do not twist the edge. The handles are very slippery and (imo) uncomfortable. I suggest you keep these knives in the display cases.
I have two, and both are in bad shape. These originally belonged to my father and his late brother. The other one has been sharpened on one side, making the grinds uneven, and has a broken tip. This one also has the etching "SOTAKORKEAKOULU" (military academy) and, as I understand, was my uncle's. The second one has a chipped edge from limbing
thin branches off a small spruce, courtesy of my father, and the pommel has been used as a hammer. Both have some handle wear, and the other sheath is somewhat scratched.
I have been toying with the idea of finding some better skilled individual to repair the knives, just to give me peace of mind. I hate when I have knives in bad condition, gives me bad vibes. I don't really care for their (lost) market value either. I myself value practicality in a knife, which these have little to me, but they have sentimental value.
