I remember seeing one of these systems demonstrated at a Woodcraft store a few years ago. I was impressed — which is, after all, the whole point of a good demonstration — at the time, but have not heard much about it since (it’s still available from Woodcraft online). The Razor Sharp system has two compressed paper wheels. The silicon-carbide coated wheel is used, with a conditioning wax for lubrication and heat control, to create a burr or wire edge. Then the slotted wheel is used, with jewelers’ rouge, to remove the burrs and polish the edge. The manufacturer claims Razor Sharp can sharpen any knife (circular blades, curved blades, reverse curved blades, serrated blades, wavy blades, and straight edges) in addition to axes, chisels, draw knives, gouges, head knives, lathe tools, leather punches, needles, planer blades, scissors, v-tools, “and more.” They also unconditionally guarantee the system. The 6″ Deluxe kit (two 6″ dia. wheels 3/4″ thick with 5/8″ arbor and 1/2″ bushing, grit pack, and instructions) costs around $44 (at Oso Grande Knives and Woodcraft).
Have any Toolmongers used the Razor System? What did you think?
