Vintage DIY: Home made roller sharpener for safety razor blades

The internet archive has a lot of odd stuff. One of the things I’ve found is a copy of Hobbies Weekly from 20th March 1934. And as I was idly flipping through, I spotted this:

The design is simple, as benefits a tool made from odds and ends. Some pieces of wood, some spare leather – as we all have laying around – and a fe hours of tinkering. No gears, the two rollers were close enough to drive eachother by friction.

I’m half tempted to make this at some point.. not for using, but for the tinkering.

It seems easier to simply palm strop, no?

Interesting, but actually a leather strop and not a sharpener.  It should work, assuming the blade is consistently held at the proper angle.

If you try making one, Hans, be sure to post the pics so we can all see your pence-saving device!
