Thread: Knife sharpener - Scary sharp or Wicked Edge

One never seems to see these knife sharpening systems coming up for sale second hand, that tells me they are either really good value and no one wants to part with them...or they are junk.
Me, well I am one of the old fashioned ones that use a sandstone water wheel and carborundum stone and a quality steel...advice I would give to anyone sharpening knives is to get a jewelers loupe and closely inspect what you are doing.
