Review on HFS Diamond Knife Sharpener Sharpening by Kyle Hood

I'm not a knife expert. I bought one of these about 15 years ago to replace a flexible metal disc knife sharpener and I am very happy with it. It needs to be on a non-slip surface, so on a countertop you should place it on a damp towel or rubber mat. After that, the only real trick is to hold the blade at the same angle that the knife was previously sharpened. There is a trick where you draw on the edge of the knife with a marker before you trace the edge across the surface of the diamond and then check that you've removed the ink evenly but after sharpening a few knives you can feel it , if you are not in full contact with the grinding surface. In general, I think I get better results than using a flexible metal wheel and sharpening with a round grinding wheel. I have sharpened many knives over the years and use it to keep my everyday knives sharp. I have several premium knives with lifetime sharpening. I use them so seldom that they are still very sharp. I'm considering getting something like the Lansky sharpening system to sharpen premium knives at the 'optimal' angle. I don't often stick to the "optimal" angle, but knife makers always mention it, perhaps because they sell knife sharpeners and sharpening services. For now I'll take this sharpener and start at 200, then increase the number up to 600. A puff or two at 300, 400 and 600 will do if the knife is already mostly fine, then hits at 200 if you damage the blade or wear hard.
