KME Knife Sharpening System Diamond Kit - $250 Great system, but I need to sell it. Purchased it 10/22/14 and it was only used on two pocket knives. My cost was $320.60 with the full diamond kit and these accessories: the stand, leather strop, 4 micron stropping liquid, extra x-coarse diamond hone, pen knife pro jaws, tapered diamond rod for serrated blades and the Hewlett JewelStik 1-2-3 (three grits) diamond hone for re-curve blades (or any knife with a concave blade design).
