A curved metal typing ruler for a variety of purposes including:
* curved erasing shield (especially useful for carbon copy packs to prevent carbon transfer)
* elite spacing letter counter
* line counter
* 8 inch ruler
The curved ruler comes with a convenient tab (here labeled “Elite”) for grabbing with one’s thumb and forefinger for placement into as well as removal from a carbon pack. They obviously came in both Pica and Elite versions to cover various typewriter typefaces.
Our friend Joe Van Cleave cleverly uses one to cleanly tear off paper from his Kerouac-like rolls of typing paper.
