I find myself wondering, given the level of decoration, if these weren't "gentleman's" tools, not intended for actual use.
I'm tempted to argue that multi-tools go back farther than that...

...but I guess that would be unfair. I mean, the really old ones don't have a corkscrew or church key, even (an omission I also note on the examples Branson posted), so how can they be multitools?
