Upgraded RUIXIN PRO RX-008 Professional Knife Sharpener with 10 Whetstones, 360° Rotation Flip Design Fixed-Angle Stainless Steel Kitchen Chef Knife Sharpening Kit Abrasive Holding System Tools

Overall works great. I bought the metal upgrade swivel for this do to some complaints on longevity on original swivel. I can't attest to that because I upgraded it right away and kept nylon swivel as a back up. I usually use a wet stone and hand sharpen by feel and eye. However, that can be tricky and time consuming. This hasn't sped up the process that much for me, but it does keep a consistent angle for the knife bevel. I also bought a competitor diamond stones with similar size plates. They actually fit the RUIXIN PRO RX-008. I chose diamond plates for when I need to re-bevel and shape a severely chipped or dull blade. The stones are not bad but those are better for maintenance sharpening and upkeep. Where as diamond allows you to reshaping and re-bevel really dull blades. The key to sharpening is that you have to shape primary edge first then Secondary edge (cutting edge) last. I could be using the edge names backwards, however, the point is for extreme sharpness do as follows: 1. Make sure blade is straight, not bent. 2. Thin out main edge a little. To do this pick a flatter angle than cutting edge angle. For instance let's say you want a 17 degree cutting edge. On this step you sharpening or thin to a 10 degree angle. 3. Now that step 2 is done you increase angle to 17 degrees and sharpen. What I do is clamp down blade and bevel edge evenly until my nail catches a burr on opposite side of blade. Then I unscrew the blade turn over and repeat. Depending on the dullness of the blade will determine what grit to start with. If your knife is really dull you want to start at lower grits and slowly move up to next grit. At the very end use a flat strop or straightening chef hone. This will remove small burrs and straighten the cutting edge (pretty much microscopically). If you can see the burr with the naked eye that is not good. Also, One last thing do not use the clamp swivel clamp for sharpening (meaning pick a side to use. ) personally I chose hexagonal (allen wrench screws up). Even though this increases the sharpening time, it does two things for you, keeps same angle, if you flip clamp angles are different. So unscrew blade and manually flip blade and re-clamp. This Keeps you safer and keeps same angle. Because if that spring loaded part were to give out while you are pivoting it you could severely cut yourself. The swivel is for choosing an angle not for flipping and keeping same angle. If the design is for that than I'm sorry it will not work as intended. That being said as long as you manually flip blade and re-clamp you'll be good with this.

This sharpener is able to get a razor sharp edge if used properly. the instructions were written by someone who clearly did not speak english as a primary language, but they are decipherable and provide great guidance on how to use. this is the second model i bought because the first one was made of mostly plastic, which became brittle and collapsed. this one is made of metal and has held up much better. four stars because i broke 3 stones using tis when they fell out. the beveled stone clamp does not hold a stone properly unless i was shipped this short a part. if you are very careful this can be prevented.

All my kitchen knives are kept sharp, with this device I can take them to extremely sharp to just plain ludicrous! It takes a while to learn how to achieve the best possible edge, but once mastered the results are remarkable. The over all quality and construction is very good and should last a long time with proper care. Beware, changing stones should be done over a table, they are long and thin and will not survive a fall to the floor. Note: ludicrous level will actually shave hair off ones skin, but is not good for kitchen use as the edge will fold easily and go dull. Very hard knives take a bit longer, but the edge lasts a long time.

Tried this out for the first time tonight. Love the concept but I've never sharpened knives in my life and while I'm super handy, it did take some practice to get it right. Easiest was touching up the edge on a basically new knife. Getting a 10 year old cheap paring knife sharp is going to take more work. A few design improvements I'd recommend. The grip for the stones seems scary. I'm constantly waiting for them to fall out. Nothing really holds them in other than a little spring pressure. One of my stones arrived broken and another only just fits in. Super sketchy to use. I'd imagine the thinner diamond plates fit perfectly. The rubber grip seems to slide around a bit. Wasn't an issue but imagine it could be. I don't get why the grips for the knife blade are Allen keys! That is a total faff vs something else you could tighten with your fingers and wouldn't wear/strip over time. Generally feel it's a useful tool that helps you do something hard to do without it, thought it was good value for money, but see how it could be better.

What I like: 1)The pretty secure mount to a table, etc.. 2) It has 2 long matching metal plates that uses more than 3 bolts for upper and lower knife adjustments and it secures the blade very very well. 3) It is very easy to use once you get it set up, preferably next to a water source for keeping the stones wet. 4) You can get the blades of your knives razor sharp. 5) It is just a matter of pulling to flip the knife over to the other side safely. What I don't like: 1) It takes time and patience to get this set up. But once it's set up, it easy to use. 2) I am going to switch out many of the bolts so they will be easier to use and tighten. I have to use a pair of pliers to get some of them tight enough to hold for any long time use and maintaining a constant angle. 3) It's tricky getting the angle you want. I down loaded an app on my phone to get the angle then I made scratch line where when I set it up again, I would have the angle I want. 4) It's a little pain in the tail screw and unscrew the bolts when changing knives, but it is what it is. This has got the most secure blade holder you can get.

I used this on two knives. It broke on the first one, but I tried working it out to make it through. First the instructions are terrible. I could make it past that because the process of sharpening knives isn't too difficult. As soon as I started using the sharpener, two screws started stripping. The screw holding the guide rod to the unit that holds the stone stripped and wouldn't maintain the position needed for sharpening. I even tried super gluing the rod in place and it held long enough for me to finish the two knives I was working with, then it came undone. Two of the stone provided cracked in half just by attempting to use them. The instructions show stones attached to a base piece that fits in the handle piece. None of the stones came in with the base attached and there wasn't any base pieces provided. Long story short, none of the retaining pieces can be screwed in to maintain specific angles, none of the screws that hold things in place work because they strip out also. The stone provided are cheap and break apart with very little pressure, let alone day to day application. PLEASE, DO NOT PURCHASE THIS CHEAP HUNK OF JUNK! I've purchased two of these units, the first one lasted about two months before it broke apart and was useless. I figured it was user error and purchased a second sharpener, same type, but more expensive. I thought I would get more for the extra money. This one was broken within five minutes of use. TERRIBLE PRODUCT AVOID IT LIKE THE PLAGUE!!!

Impressive. Disclaimer, I didn't use the stones. I went straight to the RUIXIN PRO 8 Pcs Diamond Knife Sharpening Stones sold in here and sharpened 5 knives in an hour. The reason it took that long is these knives haven't been properly sharpened in a decade and were closer to hammers than knives. Three of the knives were Shun Classics which are my wife's favorite. I can't say I know how she did it but one of them had several 1/16th or bigger chunks out of the edge. I didn't have much hope for that one but I stayed on the lowest grit in the diamonds and basically removed a 1/16th all the way along the edge. Worked great, but took a bit. That one knife was easily half an hour. All of the knives easily pass the paper slicing test. Pretty impressive at the price. Yes, it's all a bit finicky and you have to wash all of the china off the parts to get them working properly (I used wd40). The collars can move and change your angle if you're not careful with them and I suspect if you have no mechanical knowledge at all this could be tricky but all in all I don't regret the purchase.

I got this to replace my Lansky system that functions basically the same way. This system offered a few improvements, so I figured I would check them out. I must state that I also bought the upgraded swivel joint and the upgraded diamond plates. My Lansky sucks for pocket knives. It also struggles to hold any knife in the clamps. There is a tiny notch they are supposed to go into and it pinches down. What usually happens, though, is that the knife will start to wiggle free as there is not enough clamping surface area to adequately hold the knife. This system has a MUCH larger clamping surface. This system has a C-clamp mount that lets you attach it to tables or counters or workbenches. That is also a huge upgrade. The Lansky has predefined angles you must use, which of course actually change with the size of the knife. So a 17* is not always 17* if the knife blade is wider or narrower and for pocket knives, it was just awful. With this system, you can adjust the angle to anything you like. This was my number one reason for upgrading to this system. For the item out of the box, it gets 4 starts over all with a few 2 star features: -The stones do work but they are VERY soft and do not work well. You definitely want to upgrade to the diamond plates. -The swivel joint works just fine and I probably did not need to upgrade it, but the pro joint does work better. So I am not upset that I got the upgrade. -The plates that hold onto your blade come with some protective plastic clips that attach with double sided tape. These are crap. Just throw them away and get some masking tape. It works just as well at protecting your blade from scratches and does not wiggle around like the plastic pieces did. Once I made those modifications, it is a truly incredible sharpening system for any purpose knife from pocket, to bushcraft, to kitchen. Just do not forget to take a leather strop to your edge when you are done.

a Chinese product that doesn't work

Très bien

Bueno

This was great for sharpening my knives. Is does leave stone dust on the floor but that is to be expected.

Everything is work, but the sharpening stones are poor quality
