What is this thing?

Is there a name for this sort of object? I need something like this, but don't know what to type into the webs ( lemmy.world )

I'm going to convert my computer chair from pneumatic to static. I'm currently using plastic clasps that are held on with jubilee clips, but they're not great and need replaced (I'm a heavy lad). A sturdy metal version would be better....

Found this when we were cleaning out a family member's basement. I don't know anything about who owned it other than that it was a family member from a few generations back. ( lemmy.dbzer0.com )

There's a patent number on the smaller of the blades near the hinge (2037943) that led me to a US patent from 1936 but it didn't tell me a lot about this particular knife. Any information on time period, brand, model, cleaning/restoring, etc is helpful. Thanks!...
