Input:
Really gets a sharp edge on my knives. I've had a set of Sabatier knives for about 15 years. Other manual knife sharpeners created  nicks on the edges and the sharpness has become duller over the years. The AccuSharp has brought them up to like-new sharpness. They now slice vegetables and meat like they did when new. I don't  expect these knives to last 60-70 years so this sharpener does just fine for me.
