Acquired A-Z (1-25) Gray Pressboard 1/5 Cut Tab File Guides, Letter Sized (Oxford Pendaflex)
25/Set (PN 925)
I saw these while browsing through a thrift store and correctly clocked them as thick tabbed dividers though the person who rang them up for $1.50 thought they were folders because of their heft. 

I’ve been wanting some for use with 8.5 x 11″ index cards, but thought that most major stationers had quit manufacturing them decades ago. It turns out you can still get them from Tops via a variety of different office supply outlets, though closer to the range of $15-40 per pack. I’m sure these will work wonders in my Shaw-Walker filing cabinet

Interestingly, one outlet I saw was pitching them for dividing files within a single a folder, but I’m guessing they weren’t aware of how these were used historically. (The entire group of 25 would fill up a standard manilla folder all by itself!) It’s sort of a shame that they only count up to 25 instead of 31 so that one could also easily use them as a days-of-the-month tickler file.

Acquired File Tab 3 Inch Punch (McGill Incorporated)
A punch for making file tabs of 2 1/4" x 3/4"
P/N 68500
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.
