Bill and Presumed, The Lee Valley paper hones are marvelous, I bought the two coarse grades. I took a inexpensive Mora and gave it a theoretical survival workout; shaved some shelter pegs, fuzz sticks for fire, amputated my foot, fought off a wolf pack- the usual. I applied the papers to my PSK and had the blade serviceable in no time. I cut to fit the surviving sheets with one fold, so it rests inside with my Rite in the Rain, knot card and crib sheet. That gives me two full sheets of each. The diamond hone takes up a little more room, but resides under paracord on my sheath.
