Already renowned for being an innovator in the knife and tool sharpener industry, Lansky continues that tradition with the new Tactical Diamond/Carbide Rod Sharpener.
Despite claims to the contrary on late night infomercials, there is not, nor has there ever been, a knife or cutting tool made from a material so invulnerable to wear that it won’t dull with use. This means that a person who uses knives routinely must also resharpen them. But recent generations have seen a move away from old-fashioned home cooking to fast and frozen foods, and from processing one’s own game and livestock into packaged meat. The results have been kitchen drawers filled with blunt knives that might never have been sharp, hunters who have a messy time field-dressing deer, and—worst of all—quality blades that have been ground away by unsuccessful attempts to sharpen them.
As fewer people spent the time necessary to “feel” how flat a beveled edge lay against conventional honing surfaces, manufacturers were faced with a challenge: creating resharpening tools anyone could use to bring a dull edge back to at least functional sharpness. A young sporting goods store manager named Arthur Lansky LeVine accepted that challenge. LeVine calculated that the fundamental problem lay in determining, and then precisely maintaining, the best angle for re-honing nice, flat bevels that terminated in a very sharp point at the cutting edge. Too steep an angle, and the cutting edge is untouched by a honing surface; too shallow, and the cutting edge is worn away or folded over, making a knife even duller than when you began.
In a factory setting, manufactured knife blades are precisely shaped and sharpened by “fixturing” them in a device that keeps them immobile in exactly the desired position, while an equally controlled grinding surface wears away regulated amounts of metal. LeVine calculated that if a handheld tool could control angles between hone and cutting edge bevels the way manufacturers do, then virtually anyone should be able to sharpen a knife to razor keenness.
