Faster and easier and better results than I expected. I’d been using a well rated manual sharpener that required frequent use to keep even moderately sharp edges. Advertisements of knives that easily cut a neat slice from the edge of paper seemed implausible as even after my best manual attempts I couldn’t do that. With just a few strokes through the sequence of slots on this sharpener, each of my good knives passed that particular test. More important, they do seem to work better at real kitchen tasks.

I've had some pretty decent knives for a few years that have slowly been loosing their edge. I've pampered these knives, they've never seen the inside of a dishwasher, are kept in their sheaths and are stored away from wives and kids who would use them to pry open jars... That said after years of honing and use they became less sharp than they were. The purest's on Reddit say use a set of stones... that takes time and practice to get right. The rest of the folks out there suggested folks like me (and you) might be better off to use this model electric sharpener.
They were right. Knives that were not worth more than using as a screwdriver are now razor sharp. The good quality knives I have could probably cut bullets in half were I in a Kung-Fu movie. This thing works. It's easy and relatively quick. Took a few runs to really get the hang of it; after 20 minutes I'm putting it away as all my knives are crazy sharp. Almost makes me want to abuse them so I can sharpen them again... Almost...

I read reviews and watched YouTube for basically 3 years before I finally bought this thing. This thing is absolutely frighteningly scary. It's sharpens knives to a truly scary extent. Have you Stones I've used the stuff you get it the store to sharpen knives... Those simply are not in the same category as this. This gets my blades to a level of sharpness that I can only describe to be that of a surgical blade. It really did change the way I wash dishes with knives in the sink. You have to be very mindful at all times where your knives are especially underwater, or when you're reaching in drawers. It only takes a slightest touch, the slightest contacts to cut yourself. What's scary is that the blades are so sharp that when you cut yourself the way it cut your skin is so clean. Like I said, surgical. If you can afford this, you should get it, but you really have to rethink the way you move about in your kitchen.

Wanting happiness in the household and kitchen, we recently purchased three new high-grade kitchen knives from a brand name Japanese manufacturer. These were designed to replace a set of similar sized, but well used/worn knives from a German producer that were no longer getting the job done. To complete the cutting tool makeover set we popped for this sharpener to keep things in tip top shape. The sharpener was far and away the best purchase of the bunch - they restored the old knives to "like new" condition, and gave an even better edge to the out-of-the-box set of new knives. Assuming this unit holds up over time we are expecting decades of utility from our kitchen knives, and lots of tasty meals more easily prepared because of the super sharp knives!

I am a Chef and have well over 100 knives. Until I bought this sharpener I was sharpening laboriously by hand using a wet stone. I was a little concerned that the sharpener would take a lot of metal off of my valuable knives, and it turns out that the course grinder wheel does take off a bit of metal from the blade when first sharpening a very dull blade. However once the blades are sharp you can keep them razor sharp using the polishing wheel witch takes off almost no metal from the knives.
