AnySharp Knife Sharpener, Hands-Free Safety, PowerGrip Suction, Safely Sharpens All Kitchen Knives, Ideal for Hardened Steel & Serrated, World's Best, Compact, One Size, Black

It's a generally good product that does exactly what they say it does, sharpens your knife! Others have alluded to the fact you can see little metal shavings coming off the knife so you really feel like it's doing something. I would then of course suggest you use a honing steel to ensure that there are no micro-metals still on the knife, I'm sure you wouldn't want them in your food.The gadget itself is a little smaller than I imagined it would be, about the size of a tangerine or small apple. The suction isn't the best, and for safety I really would recommend reapplying the suction after every stroke of the knife to ensure it doesn't accidentally slip, but that could also be due to the worktop I have been trying it out on. I imagine, on reflection, that if I used it on my glass hob I might get 3-4 swipes before any movement started to occur...Okay, update. I went to try and am now updating my suction rating to a 5/5. Couldn't get it off the glass when I tried and to this company's credit, it probably suggested that somewhere, I'm just not fantastic at reading every single word... You know what I mean, right? Long story short, I'd do it on smooth glass where possible (Of course not on the window!!) Moving on...The knives themselves feel sharper straight away after using, though I will state that I haven't yet tried it on the types of serrated blades it promises to be able to sharpen. I bought this after chickening out at getting good with the Whetstone I had also purchased... I have every confidence that this will keep my tomato slicing razor thin, until I work up the courage to give it a go! And it's so effective that I'm sure it will take me even longer to jump that hurdle... lol.Thanks for reading

My kitchen knives seem to get blunt quite quickly so this sharpener is handy to have - small and compact and does the job. On trying it out the first time I found I couldn’t use it on my kitchen worktop as it didn’t hold the suction and kept moving, however, son in law to the rescue and he tried it out on the tiled surface of the kitchen window sill and the suction was great - stayed firm until opened to release. Happy with purchase.

Every knife in the house is now sharp and a pleasure to use, which is what these small sharpeners are meant for. Cheap as chips and easy to use, integral clamp makes them safe when used on a smooth none porous surface.

Bought this after a slight mishap sharpening a knife in which my finger came off worse. Sticks itself to the kitchen worktop by a suction lever and let me tell you it won't budge - it's not going anywhere! Simply place the blade in between the V shape sharpening faces and draw the knife towards you 2 to 3 times and it's perfectly sharp!

This is the second one we've purchased gives a knife a great cutting edge just a couple swipes and the knife is sharp again.. the suction cup makes it easy just to use one hand keeping your other hand away from the knifes blade.

Easy to use and very effective.

It's ok, sharpens a bit, but not the knife transforming product it claims to be.Ok value.

First one I bought was a fake one.Amazon kindly refunded me Andi bought another.Please make sure it says sold and dispatched by Amazon, or you likely will receive a very poor quality fake one.The real one is pretty good, it does sharpen your knives and is very easy to use.I wouldn't say it makes them super sharp or razor sharp, and it will not sharpen like a stone would, but for slicing vegetables it is sharp enough.
