Back before the $200 DMT lapping plates and ultra fine grit ceramic hone progressions, a skilled hand would sharpen a razor on a rock that he kept from dishing out by running a dressing stone around the perimeter of his hone. I don’t know if razors were more geometrically correct then, but I doubt it. The skilled hand would use all the tools available and apply the things he learned to create the best shaving edge he could. The best do exactly the same today and take pride in their ability to create the smoothest sharpest edges we all love. The creator of this concave elliptical lapping plate was one of these type of folks. Although in a trip to the old country, he was astounded that an 80 year old master grinder told him he was doing it wrong. After many laborious renditions of trying to create a consistent, reliable and repeatable method for creating this convex elliptical hone surface, I think he hit it with what I call “The Jarrod Plate”. I purchased convexed hones from Jarrod and found that I was able to get imperfect razors into good shaving condition where I failed to have the experience and knowhow that others had acquired. I also found a couple of cases where I just was not impressed by edges done in modern methodology I knew should be better. I applaud Jarrod for pursuing what I believe an incredible advance, an aluminum elliptically concave lapping plate for use with commonly available sheet abrasives. Now I expect many fine and accomplished honemeisters to completely reject this method because they are so good at what they do. I encourage them to ignore this methodology because it is unlikely that their long standing skills and practices will work on these surfaces. Using 80, 120, and 240 grit silicon carbide wet/dry sandpaper I resurfaced my covexed arks and Belgian coticule into the new convex ellipse shape. I also did my Naniwa 12k. The result is very pleasing to me visually. I’ll report back in as I work with them.
