The new modern, designed by a guy who didn't have to use it daily?I’d have said “keyhole saw”, but never seen one with what looks like a hacksaw blade on it.
I suspect much-older than that. I have several keyhole saws of a similar style, I haven't used mine in a long time as I don't have any call to use them much these days.I think that design is 30+ years old
Probably. I know when my daughter got hers in a tool kit as a young child, and it predates that by quite some time, but I never noticed them prior.I suspect much-older than that.
