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.

Good sharpener
Works really well by attaching itself to the kitchen counter, stays in place and it sharpens knives well. A nice simple design.

Perfect knife sharpener
Very simple to use. It does what it says on the tin. I think it might contain a touch of magic. Its amazing how sharp my kitchen knives are now, and it takes just seconds to get a very sharp edge. Well priced and very nice presentation box.

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.

The best purchase you'll make!
This is a fantastic bit of kit! I've tried a few different knife sharpeners but they've always been either average or awful, this however is amazing and has sharpened even the dullest of my knives. It's so easy to use and takes up no room in my knife bag. I will definitely be buying the larger version of this.

Good for household use
I think it does the job okay, I only bought it because my knives were getting really blunt and I think it did the job. I wouldn’t say it was the best sharpener out there but for the size and ability to store it was good enough for the job. It’s little but it comes with a suction on the bottom so you don’t have to hold it nervously because it will stick to your countertop. I am pleased with it, just to help with the knives but I wouldn’t say it’s for professional purposes just homely needs.
