The Underwood Multi-tool (c. 1850)

Decades before the first Swiss Army knife (1891), London’s Underwood of Haymarket crafted this "harped" pocket kit. Designed for Victorian sportsmen, it features a hoof pick, saw, and corkscrew. A rare 19th-century masterpiece of portability.

I know there are blacksmiths around -- who can tell us just how hard this is to make?

Look how the big drill isn't consistent! I can recommend _One Good Turn_ for the history of threading.

Hello im a blacksmith. And alsp trained under a verry good farrier for a time
This is not espacialy hard but is time consumeing

It seems like its been made to be impossible to separetly turn each hoofpick?

Makeing the thing

1 create loops by bending thin bar
or upset(widen) ends of a bar and punch a hole in each (more time consumeing)
2 bend the back of the lyre shape
3 pass thin bar through the loops / punched holes
4 make the tools and flatten the ends that you will wrap around the thin bar
5 repeatedly heat the flattened area of each tool and wrap the flattened part around the thin bar

This is easyer to make in a coal/coke forge

Also its possible to get each tool atached prettly stiffly so they dont jangle around but i would probably add something so when they eventualy loosen you can lock them in place in their compact position

To do this id add another thin bar for the tools to rest against,and another on a rivet that slides over the other side to hold them in place

- but i cant figire out how to describe this part well

@festlicheameise @clew @Adrenochrome Yeah, I'm intrigued by that little sideways bump on the tool bases.

I suspect it actually acts as a detent so that pivoting the tools out requires outward pressure on the spine, but click back into place when upright.

@timmc @clew @Adrenochrome oh yeah that could work if theres a little flex in the lyre and they are still allowed to turn without being under too murch force it will act aas the spring and hold them all in either the open or closed position

That would be verry good design if it can work

I’m curious about the letters stamped in - what does it take to make crisp tiny impressions? Steel? Is that probably machined or cast or???
