Hard to explain. Looks like a screwdriver, but instead of a flat end to the blade, there are two protruding parts, one at either side - or a screwdriver blade with a notch in the middle. Used with special nuts that have two holes, to accommodate the protrusions on the tool.Sideways on, it would look like this (but smaller!)------------- | -- | | -- |-------------

Perhaps a driver for security screws.

What is this tool called?

They have been used from the year dot. Saws inherited from (at youngest) my father used them, and are probably at least a hundred years old.

Mine (modded a 'driver) is for doing up the nipples when building bicycle wheels. It's for the stage where the tensioning is just beginning but not worth using the spoke key and the notch allows for the end of the spoke protruding in to the slot - it shouldn't protrude but sometimes the spokes aren't to the exact length.

So close! Yes, railways, and yes, axle nuts, but sadly the Romford tool is too small. I need a larger one, for the nuts on a (Meccano) Hornby 0 gauge loco, from the 30s.
