The RADA removes metal by scraping it off, so do other carbide sharpeners. However, like when one uses a file with lighter and lighter pressure, the same should be done with carbide sharpeners. A couple of very light strokes with a diamond file or strokes on a leather belt will clean up the edge as well.
One thing that cannot be done as easy with the single bevel, the laminates, No Mercy that I do with my single bevel Hills and Grizzlies is forward flat side serrated cutting teeth. On those I get them sharp enough to cut hair, then with the raw corners of a files with safety edges, at a 45 by 45 degree angle, I serrate the beveled edge. Then flat file the flat side with either a file a a flat diamond hone to remove the chunky stuff, then lightly dress the beveled side as well. This puts very clean little concave serrations that are super sharp and on the side of the single bevel flat, which is the direction that the head is rotating towards. A softer metal needs an edge that can hold up to initial hair and bone contact. Regardless of what some will say, this does not jam up with hair, bone or gristle when going through a deer.
