It's excellent and easy to use for keeping your knives sharp.
This sharpener looks great with it's walnut and steel construction with a pair of ball bearings keeping the rolling movement smooth. You shouldn't be using it near any food so it will stay clean for a long time. The multiple sharpening surfaces offer great options depending on how far gone your edge is. I already had a manual 2 ceramic wheel sharpener that works well (Minosharp) but it's a little finicky at times and can take a while. I wanted to try this as it's been recommended to me frequently. I stuck with the 600 and 1000 grit wheels since my knives didn't require the aggressive 240 grit wheel. Finding your blade angle is the most difficult part. I had no idea anymore what mine were so I tried both angles until I could sight down the edge and it lined up with the drum surface. Sharpening was easy. Use the sound of the wheels as a guide to how far you've sharpened the edge, it'll start out rough and grating then quiet down as less material is taken away and the edge is coming into the proper profile. It's especially noticeable with the 1000 grit wheel.You will still need a honing steel to finish off the edge after sharpening. You should not be sharpening your knives frequently, you should be honing them with a steel. Only sharpen your knives if honing does not regain the edge that you require. And do not use a diamond coated 'honing steel' as you have no control over the edge angle and it is very, very easy to ruin a knife that way. That said I have a couple of issues with this product. The wheel height is a limiting factor as the working diameter is something just under 2" although I would recommend not exceeding a vertical height of 1.75" while sharpening. This excludes sharpening my Messermeister and even my Furi Coppertail couldn't be fully sharpened near the handle. The other is the price. While it's a high quality product there are other options out there for less money that perform similar functions. At $100 this one seems near the top of the market and, while it's a great sharpener, I'm not sure it commands that kind of price premium.

Fast and easy to use. Takes out the guesswork and is great for home sharpeners.
tl;drAll of the knives were quickly sharpened to a point where it was once again a joy to cut through tomatoes and bell peppers. I was very impressed with not only the quality of the results and how easy it was to get them, but also the speed. If you are an inexperienced or are nervous about sharpening knives, this is the sharpener for you.I've been using and sharpening knives my whole life, and I'm not young. From folding pocket knives, filet knives, kitchen knives, chances are I've used it and most likely have tried to sharpen it. I've used all sorts of sharpeners from Arkansas stones with oil, Japanese whetstones, diamond impregnated metal stones/plates, and even some grinding wheels. I'd have to say, the hardest part of sharpening, and this applies to all methods and tools, is keeping a consistent sharpening angle and pressure. In the past I've done free-hand, used steel guides that clip to the knife spine, clamps and angled rods, pull through sharpeners, etc., all with mixed results.So I was pretty excited to see NBHR flip things around and instead of the stone being stationary and the knife moving, their system keeps the knife stationary and moves the sharpener. The unboxing experience was what you would expect from a higher end product. The were instructions on top, including a QR code to online instructions, and the sharpener components were snuggly held below it in black foam.There are three major parts. First is the knife holder. This beautiful piece of dark wood (I'm guessing walnut) has a carved out holder for the sharpening "roller," so you can keep it out on the counter. The edges are beveled at two different angles (15 and 20 degrees) which are clearly marked with numbers carved into the wood. On the beveled faces, there is a softer black strip of silicone or similar polymer material that covers some pretty strong magents embedded in the wood.The sharpening roller is made of the same wood and is about the diameter of a Red Bull can and is about 3 inches long. On each end is a diamond impregnated disk with a grit number printed on it (240 and 600 grit). There is a rubber/soft polymer ring around the edge of the sharpening disk to help it roll smoothly. These disks are screwed into a steel shaft that goes through the wooden center piece and there is a nice sealed bearing on each end. This gives the tool a very smooth rolling feel. Just the right weight, just the right feel to the roll.There is a third sharpening wheel that comes with the set. This is a white ceramic material bonded to the same steel wheel base as the other sharpeners. There is no grit number printed on the ceramic, but the online information lists it as a 1000 grit hone.Using the sharpener was a piece of cake. There were no messy oils to deal with (like an Arkansas stone). No pre-soaking periods like a whetstone. Like a diamond plate sharpener, the NBHR sharpener is ready to go as soon as you unbox it.To start, you will need to know what angle your knife should be sharpened at. Generally speaking, American and European knives are sharpened to 20 degrees and Japanese knives are sharpened to 15 degrees. Once you figure out the right angle, you just stick the appropriate side of wooden block to the side of the knife, with the knife tip pointing away from you, and put it on a firm, steady surface like a countertop. The strong magnets in the angled base will hold the knife without slipping. Both the guide block and the spine of the knife should sit flush with the work surface.Next, take the sharpening roller and place the side labeled 240 against the knife edge and using a gentle pressure towards the knife, roll the sharpener back and forth over the length of the blade. Speed is not important, so there is no need to rush. Just smooth, steady motion. For longer knives, you may need to work the sharpener/knife in sections as the tip may deflect a little, changing the sharpening angle as you get further away from the guide block. You will feel and hear the sharpener working. As the edge gets sharpened and refined, the sound and feel are smoother.After a few dozen passes, a burr will be created on the side of the blade that's not being sharpened. ("Pulling a wire" in knife sharpener speak.) You can feel this burr by running your finger across the width of the blade (perpendicular to the blade EDGE) from spine to cutting edge. (NEVER run your finger along the blade's cutting edge!) You will feel a little ridge at the cutting edge. When you have a burr along the entire lengths of the blade, you can flip the blade over, with the knife tip pointing to you. Repeat the same process, rolling the sharpener along the blade until you pull a wire along the entire length.Once you have sharpened each side, you may need to make a couple passes on each side to clean up any slight burr that may still exist. At this point, it's time to step up to the next grit. Flip the sharpening roller over and repeat the same process using the side labeled 600.When this is done, remove one of the sharpening wheels and replace it with the ceramic wheel by unscrewing it from the roller. Then repeat the sharpening process for the third and final time.I was very happy with my results. I sharpened several Wustoff knives that had not been sharpened in an embarrassingly long time. I also sharpened my go-to chef knife, a 12" Victorinox. I found that the Victorinox blade was wider than the diameter of the sharpener. To get around this, I put a cutting board next to the knife. This gave me a higher surface to roll the sharpener along and it maintained proper contact with the cutting edge the whole time. I also sharpened a couple cheap Japanese knives that I use (petty's). The NBHR sharpener made quick work of putting a good 15 degree edge on these lower grade knives. I'm sure it would treat nicer Japanese knives just as well. I just don't currently own any. :(All of the knives were quickly sharpened to a point where it was once again a joy to cut through tomatoes and bell peppers. I was very impressed with not only the quality of the results and how easy it was to get them, but also the speed. I was able to sharpen five knives in the time it would normally take to pre-soak the whetstones. I highly recommend this sharpener. Especially if you are an inexperienced or are nervous about sharpening knives. It's very easy, fast and safe. It does a superb job tackling the hardest thing for home sharpeners to master, keeping a consistent sharpening angle and pressure. The Amazon price is currently $79, list is $99, so it's a great value. (A quality whetstone will be about the same price and you'll need three of those!)If I were to suggest any improvements, it would be to label the back side of the sharpening disks with the grit. I think with extended use, the printed grades on the sharpening surface will wear away. Adding a separate groove to the wood base to hold the honing disk would prevent any parts from getting lost.It would also be nice if there were other disks that could be purchased. Both for replacing the original disks in case they wear out, and higher grit disks for people that want to take things to an extremely sharp level. (I've seen some people that regularly sharpen to 5000-8000 grit and some sharpen their super fancy/expensive Japanese knives up to 15000.) None of these wish list items is a deal breaker by any means.
