Chef'sChoice 15XV EdgeSelect Professional Electric Knife Straight and Serrated Knives Diamond Abrasives Patented Sharpening System, 3-Stage, Black

As the title says. Keeps our Shun knives sharp at their 15 degree angle. We cook almost daily and sharpen the knives maybe every 4-6 months.

Be careful! This sharpener will completely rejuvenate your knives. My wife and I both cut our fingers because we had become used to working with dull knives. Nothing serious, but we were surprised by the razor sharpness.

I effectively sharpened all my knives, after many years of neglect. The process is practically fool proof, and the results are amazing. My only recommends are, do not apply down pressure on the knive, and take a full 5 seconds to move the blade through the machine. This machine creates a nice edge, which will hold up, and make the next sharpening much quicker.

So far I just sharpened a couple of big and small kitchen knives . The small ones were razor sharp in a few passes. The larger ones are now plenty sharp enough with maybe a dozen or so passes. I assume from what I know about knives , the big ones which were done by a knife sharpening service may need a little more work to be razor sharp, but they are great for me as is. This is expensive , but it works as advertised IMHO. When I gather some courage , I'll run my expensive Emerson and Pro Tech knives thru and see how they come out. This will save me tons of money in sharpening services and returning knives to the factory with insane shipping rates these days

Amazing! It works wonders even with the cheapest knives. While expensive, I think it's worth it.

The instruction book isn't very good. Sharpening the knives are simple enough, but the text does not relate to the desired diagrams. It is not immediately obvious what is the front and what is the back — which is extremely important. The book says, never sharpen the knives from the back.After a while, it was easy to figure out, and the results were excellent. Dull knives became very sharp with a modicum of effort.

This is a great sharpener. I have just average knives. Nothing high end, but just decent quality. This sharpener has made these knives top notch in performance with their sharpness. So now, I have no need to replace any knife. Well, worth the cost!

actually sharpens knives.
