I have one, solid leather from Levi's. Purchased someplace like Macy's. Has only 5 pairs of holes, not infinitely adjustable. Shoemaker can add more to your spec's. http://www.amazon.com/Levis-Bridle-Double-Prong-Buckle/dp/B001VN2N5A/ref=sr_ 1_2?s=apparel&ie=UTF8&qid=1399053065&sr=1-2&keywords=levi%27s+belt+double --Rich -----Original Message----- From: math-fun-bounces@mailman.xmission.com [mailto:math-fun-bounces@mailman.xmission.com] On Behalf Of James Propp Sent: Friday, May 02, 2014 1:37 PM To: math-fun Subject: [math-fun] Math belt I have an old belt that I'd like to replace with a new one of the same design. I call it my "mathematician belt" because it has two tongues instead of just one and they can be fit into a 2-by-38 grid of holes. (One could also call it a person-of-variable-girth belt, but I don't.) Has anyone seen such a belt, or know who makes them? You can see a photo at http://jamespropp.org/belt.jpg . I bought it at Old Navy a decade ago, but nobody there recognizes them, and I haven't been able to find them on the web.
