Well, no matter what the origin or age, it still somehow seems "special" to me. Someone had need for a dual purpose type of tool like that, and made it with what was available and at hand at whatever time and place. May not have had the knowhow or ability etc. for folded steel, but he knew what he wanted and did have enough skill to hammer and shape it into what was needed. Crudely made? well even all the great artist were students at one time. Terry stated he had seen similar at a Scandinavian museum, and being bought at a shop in Newfoundland, well, the two do seem to kind of go together, as well as being bought in a shop, the knife/saw may always have been protected somehow, (not being buried) thus no rust, corrosion etc.. Now, IS it very old, a Viking sort of thing?, or something much more recent, I don't know fella's, but their just SEEMS something special about that thing.
