Aluminium alloy Knife sharpener system 360 degree flip Constant angle Grinding tools Grinder machinewith 4pcs stones

First time using it, worked perfectly. By luck I happened to set the angle perfect to the blade grind and in a few minutes I had a 4'' fixed blade knife sharpened. You can use higher quality diamond stones from other more expensive companies or even swap out the stone holder and put in a flat, round or triangle file. When I turned it over I let it snap into place otherwise it has a small movement to the knife holder. I tightened the back Phillips screws first, then the allen key screws second. Well worth the price compared to hundreds of dollars for the competition and very portable if you go on hunting trips. I have a knife collection and I don't use them cause I can't sharpen them. Tried using large stones and ruined my knife. Now I can keep them sharp no problem. I didn't use an angle finder. Instead I marked the blade with a marker and it just happened to be set right by fluke. All components are rock solid. Lots of videos on the internet people saying it's just as good or better than the high price models. I like it cause it clamps solid to a table or 2x4 wood etc.

This is great value for money, but people like it only after they replace some parts.The ball can be replaced with a ball bearing. Many fixing screws don't fix well enough, they can be replaced with, say, thumb screws.The centering of the ball relative the axis of rotation of the clamp is very important and not supported well by the design of the product, needs a lot of attention during work. The centering of the knife's plain of symmetry relative to this axis is also very important; so the clamp (really good one) cannot be trusted in all cases, the clamping needs validation, tricky and time-taking. The product is not very useful for the inexperienced users.The best feature is the compatibility with wider selection of abrasive materials and tools, compared with any other sharpener. Also, Amazon and other selling portals offer good selection of abrasive materials compatible with this sharpener; one important factor here is that the sharpener can use but not require the plastic mounting pad, but can mount raw stones well enough.

This works fine for the price.. However, you absolutely cannot just flip the knife. Because of how the clamp holds the knife. you will find that the angle is *substantially* different top to bottom. Rather than adjust it every time I flip, I find it's easier to just take the knife out of the clamp, flip it over, and reclamp it.

I own 2 similar systems that are less convenient to use. This sets up quickly, holds the knife securely and works well on everything from paring knives to an 11 filet knife. I do knives frequently so I run through the sharpening stones quickly. Ordered the diamond stones for longevity. The edges on my knives are the sharpest I've ever been able to get them. Overall, a great system. I'd order again or suggest to others.

Good sharpener for the money. I like it. It's better than a more expensive sharpener that I own . You can't go wrong with this sharpener.
