Knochen (Bone)

[lowtech]

...is what this tool is called here in Germany.
It usually is included in Bicycle Repair kits and comes in different qualities from "dried Playdoo" to "actual metal, but still..."

I have not seen one on here, so i thought I´d share it.

I prefer this type over the newer plate type versions,although most bikes are allen keys now

You know, that's a very clever design and good looking too!
Thanks for sharing

I had a very similar one as a kid with a bike I bought

[lowtech]

I quite like the design myself, but i have yet to find one made out of decent quality steel.
And i, too must think of my first bikes when i handle one. Nice memories.

I have one of these, although I don't use it because my bike takes allen wrenches. I'll take a pic later.

Here's mine




It says
Patent Pending
Made in Germany

So if it's patent pending, does that mean it's old?

I have such a key manufacture of the USSR in 1970. Judging by the availability of ideas such keys must appear in the early 20th century Germany.
