“Utility” features your choice of two often-requested but rarely-available body pages: Engineer Graph or Ledger. Engineer Graph features an 1/8-inch grid with bolder lines each half-inch. It awaits your schematics, assembly drawings, geometry homework, or dungeon maps. The Ledger version, of course, is ultra-handy for mileage logs, parts lists, to-do lists, or any sort of handwritten accounting.
I’ve used these notebooks for years for all of my interviews and notes while on the road. I’d highly recommend them.
