Hmmm. A very interesting device for sure Lyndon.
I've never seen one before.
Also interesting is the "knight" logo. I have seen that symbol before, on the paperwork that was included with other old multi-gadget-knife-tools from the 1970's. Here is a wrench/knife, stamped Made In Japan. (the Jack Haines Co. stamping is a promotional marking, not the maker of the tool)
So I wonder if the "knight" was a logo for the Japanese manufacturer, or the American importer?
