"School" type pencil sharpener (Highbury N5)

I do a lot of doodling and am forever needing to sharpen my pencils. The little sharpeners always seem to break the leads as do penknives.
I've been told the old-fashioned type with the crank handle are much better.
With that in mind, has anyone got one they don't need anymore? It doesn't have to have the fixing clamp - easy enough to make, and I could probably fix a problematic one.
I'm very flexible with pick-up times and days and would be eternally grateful.
