I recently acquired this knife on ebay, and was wondering if anyone knew much about them. I had never seen or heard of them prior to buying this. It has JOH ENGSTROM ESKILSTUNA SWEDEN stamped on one side and has an arrow with JE 1874 on the other. I'm unsure if that's the date of manufacture or if that's a patent date and the knife was produced later. Either way, it's in pretty good condition considering how old it is, and the only thing I really see wrong is that the base plate on the knife is slightly bent. Are these still made or are they obsolete?
Here is where the base plate is bent slightly.
