Excellent sharpener – compact, safe, and very effective!
I’m really impressed with the Diamond Edge No.1 Knife Sharpener. It’s compact, easy to use, and feels very safe thanks to its stable design. I tried it on several knives, including serrated and outdoor blades, and the results were excellent — the knives became noticeably sharper in just a few passes. The build quality feels professional, and it doesn’t take up much space in the kitchen, which is a big plus. It’s perfect for anyone who wants a reliable, manual sharpener without any hassle. Great value for money — highly recommended!

Great little sharpener for everyday use
This small knife sharpener works really well for its size. It’s compact, lightweight, and doesn’t take up much space in the kitchen drawer. Very easy to use, even if you’ve never sharpened knives before. After just a few passes, my dull knives were noticeably sharper and ready to use again. It’s perfect for quick touch-ups and everyday kitchen knives., it does exactly what it promises and offers great value for the price. I’m very happy with this purchase and would recommend it to anyone looking for a simple, effective knife sharpener

Good sharpener if handled with care
Handy little gadget to have in the kitchen. Even though it’s plastic it does have a sturdy feel to it. The suction cup at the bottom can slip when using the sharpener (minus 1 star) but being careful, you can hold the base down when drawing the knife towards you giving a sturdy feel. When sharpening a knife you can see the grindings on each pass leaving a nice sharp edge. If your knife is blunt it may take a few passes to sharpen but will do the task for you. Overall, with a little care it’s a handy tool to have around.

Great price and great gadget.
What a brilliant gadget. When my son seen it at Christmas as I was trying to sharpen my carving knife, he said "NO mum you can't use that it is too dangerous for you " . I ended up giving him my set of knives and the sharpener and he was so happy he sharpened everything in his house. I am happy he liked it as I am partially sighted and I also have rheumatoid arthritis in my hands. This gadget is a game changer for people who can use it safely. Would recommend this item to everyone well worth the money. And my son is very happy, I took am happy to have parted with it and the knives are now out of my house if I need anything else sharpened I have to ask my lovely son... 😍

Put it in your basket
Much smaller than expected. But as some of the people say; “it’s not the size that matters, it’s what you do with it” or whatever. The size really does not matter in this case. The suction function is fantastic, I was in a rush, and spilled crystal salt all over, swiped some but not all away, but this bad boy still clung onto the worktop like a champion (yes you’re still reading that knife sharpener review). I completely forgot to chop up an onion, so sharpness and speed were of the essence. At first I didn’t get the angle right and it wasn’t what Id call a smooth performance, but gave it another go and booooom, this time it was the onion that was crying. What a feeling. What a superb little piece of kit. Hope these are made to last but I wouldn’t be too mad if I had to buy another in 1 year. EDIT: having used this sharpener LESS THAN 20 TIMES I must say that it no longer performs. I expected more life..makes no difference now. Maybe I did something wrong.
