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

Absolutely amazing. Mine came with 8 stones and the set up is really solid. I have gone through and sharpened 4 of my knives with it and the edges are holding extremely well.

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.

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.

The system is good. Has some learning curve but that's expected on any system. The stones, however, are really cheap. When opening them, I could see the quality was not all there. They are thin and flimsy. The spring on the stone arm isn't long enough to apply a lot of pressure, but you're counting on a hand tightened metal surface holding a wet stone. Needless to say, it slips all the time. With that, I have to stop a lot more to fix the stone, make sure it doesn't get stuck, make sure it doesn't fall, etc. Inevitably, one fell and you can see the results in the picture. Now I'll have to wait, get new stones or diamonds and try again. What was supposed to make my life easier and help speed things up, only slowed it down. Took me about 30 min to do one knife and it's not even that sharp.

Facil de usar, es una respuesta sensacional al afilado artesanal y profesional de cuchillos .

So basically what you have here is a defective piece of workmanship.Threads are not good enough to allow the rod to mount properly into the base.The base is cheap aluminum so that the threads will gaul and strip.The bearing that allows the rod to push and pull thru the guide is trash.This is about a 22usd piece of equipment and 15 of that is the counter mount c clamp.Never been more disgusted with a piece of sharpening equipmentSending back asap and ordering what I should have ordered to begin with.I keep reminding myself I cannot afford cheap

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.
