Good: have acquired nail file and emery boards.
Better: Purpose accomplished - the shiny mirror-finish plastic of the new (rushed to shop by annoying clerk and therefore poor decision made) iPhone case is sanded off to matte finish and is less slick and more grippy. (No, I am not posting pictures to thereifixedit.com.)
Annoying: Neither the nail file nor the emery board are small enough to fit in the hollow-handled blade storage compartment of the folding saw in the satchel toolkit.
