A punch for making file tabs of 2 1/4" x 3/4"

I had been considering getting a custom punch made several times, but never looked to see if one already existed commercially. Today, while doing a 5 minute peruse of the thrift store, there it was!

When you use as many tabbed index card dividers as I do, this can be incredibly useful. It’s just the right size for doing 1/3 cut tabs on 4″ x 6″ index cards.

Acquired at Acts Thrift Store on October 7, 2025 for $2.50.
