thank you all. i've used it beside my muddy fbm to chop my LSAT book, and they both went about 150 pages into it, closed. the sage fbm got an extra page or two.

these are chops into the face of the book with the belly of the knife, not stabs. the muddy mistress got about 60 more pages than the sage on the stab. not surprising. there was probably plenty of variation in the force i used. fun, though. that test sucked. lsat, that is.
