Nice knife. Nice full tang and a stop to not want a guard on it.
Use it for many things.
But it's near roach belly design is more of a slicer. Also called scalpers some places at one time.
Why the back of the spine is like it is I don't know. Perhaps baton-ed on with something too hard.
If the knife held on it's side flexes just a little then it's good to go brawl against the wilderness and folks headed back of beyond might have considered it suitable.
If it's easy to bend and flexes easy it would work as a boning knife for deboning critters. Chase around bones efficiently and trim tight to them.
Otherwise ,breaking down a large animal quickly into manageable portions from deer to moose it should work.
It's design wants to slice. Not stab.
Compared to the bulbed flare on a butcher knifes profile than kind of helps cut steaks , your pictured knife is more like the modern butchers convex curve kinda like a scimitar. But curved more at the end/front. Another slicer.
General purpose but more.
And fancier than a cheap butcher knife which did much of society's work over time.
