Guys I am constantly sharpening knives , whether it is EDC , kitchen, filet.... well you get the point. My son bought me a work sharp and this thing is excellent. I had a couple kitchen knives I just basically spent very little time on cause my wife can tear up the proverbial anvil when it comes to knives............. I guess it is the dishwasher!! Any who, one of the butcher knives was so bad it was just short of a serrated edge I did not actually time how long it took to get it shaving but it was less than 10 minutes. If the blade is in decent condition I can have it shaving in just a minute. If ya need a time saver folks this thing will do it quick.
