I use the Lansky and other systems to keep a consistent blade angle and use the greatest angle for a working edge. The blade will last longer and the edge is just as sharp as a lesser angle edge. When I resharpen a blade, I place the holding tool (vice) in the same spot; I keep notes with the tools. To get a perfectly cut blade, I use an 8 power loupe to make certain the edge is to a point, no flats or chips. Then I use a finer stone until it is ready to go to a polishing stone (arkansas stones). With some care, a razor blade can be resharpened; I have resharpened double-edge blades and they will last for years if you need to bother.For some knives, I do use a diamond 2 stone system. These are my kitchen knives that do not take as much abuse or work. My wife makes me hide the real sharp ones high up in the cabinets. If anyone buggers the blade with his stones improperly, I won't resharpen his blade. It takes as much as an hour to recut the correct angle and only a few minutes to touch up my original sharpening. One, my Dad, would try to sharpen my knive blades with a motor driven stone and ruined each one. He didn't seem to understand the time involved. It may have been the Alzheimers. I have cut up an entire white tail deer with my folding Buck Knife. I had to break the ribs by leaning on them on the edge of the kitchen counter.
