The best knife sharpener I have ever used
I like very sharp knives, especially for Slicing onions and tomatoes, but I can’t do knife sharpening on a steel or whetstone (haven’t been taught how) so have always relied on a counter top sharpener. Until I bought a global knife, that is. My sharpener seemed to blunt my global knife so I looked for a better solution. The price of this sharpener was at first a shocker for me but frankly it’s worth it. All my knives are now properly sharp, which is a revelation to me as I still have had no formal knife sharpening training. Totally recommend this product. Quick and easy to use either way round (most of my household members are left handed) and the effects are just what I was looking for.

A BRILLIANT PIECE OF KIT
For years I have tried to keep my knives sharp using a stone with limited success. So after seeing an article in a newspaper I discovered the Global Water Sharpener. It came number one out of ten reviewed. Not cheap but what a tool. Sharpened my knives to razor sharpness so I opened the drawer and got out some old blunt knives. After following the procedure a few times they are now sharp again. Simple to use just drawing the knife back and forth, and as the sharpening stones are angled you are always sharpening correctly. Dont hesitate to buy this if you want quality.

Good but pricey
Had one of the old style wet stones for sharpening my set of Global knives which if I'm honest was a pain in the neck and over the years the knives have started to feel a little blunt. Having purchased this new style sharpener all I can say is WOW! What a difference. The knives now glide through anything put before them.I've scored it as a 4 star purely due to the fact it is a little pricey compared to other sharpeners but having used a few of the £10 ones they have always felt like they were damaging the knives whilst sharpening them (lots of metal shavings).

Worth the extra money
I've tried a variety of tools over the years to keep my knives sharp, and this has to be the best. Immediately prior to this I was using a whetstone to sharpen my Global knives which required skill and patience - when I had those the knives came out with a super sharp edge (and scuffs along the blade), but when I didn't, I'd end up with a blunt blade. This sharpener requires neither skill nor patience - it's simply a case of putting a bit of water in the tray and then using the two slots to run the knife against the sharpening stone - simple and effective. Also, because it's less faff than a whetstone, the knives are sharpened more frequently, and retain their edge.

You can buy new wheels when the wear out
I've had Global knives for 20 plus years and the sharpener just the same, but this new disign is a lot better than the old ones.

Sharp! Sharp! Sharp!
Had my Global Knives for years and had been using the Global ceramic steel to keep them sharp. Unfortunately, the steel has recently broken and I have been looking for a replacement. This Global Ceramic Water Sharpener is fantastic and in my opinion does a better job than the ceramic steel and at a much cheaper price than buying a new steel. Very happy with it and would recommend.

Global quality.
Was just about to place an order for an Anysharp Pro. Then luckily I read a review of the Anysharp telling me it was unsuitable for Japanese Global knives. Anysharp set up to give a 20 degree edge and Global knives set up for 10-15 degree edge. I have a set of Global knives and these were what I almost bought the Anysharp for. Did a quick search for a Global knife sharpener and found this item instantly. A bit expensive I thought, but so were my knives so ordered one anyway. Arrived quickly and after trying it out on my two most used knives, the results are very very impressive. Sliced up a fresh bought firm tomato like the knife did a few years ago when it was brand new. Recommended...........for Global knives.

Un buon prodotto, ma piuttosto costoso.
Nella sua categoria secondo me, tra quelli che ho provato, è uno dei prodotti più validi e che funzionano meglio.Rispetto ad altri prodotti simili, la sua particolarità è che le due rotelle abrasive sono posizionate semi immerse in una vaschetta che va riempita d’acqua, questo fa si che passando il coltello, queste ruotano e vengono costantemente bagnate, in modo da scorrere meglio sulle lame. Il risultato mi sembra abbastanza buono. La mola a grana più grossa (bianca) “gratta” abbastanza (v. foto), e si riescono a riaffilare anche lame leggermente rovinate, mentre quella più fine (rosa) serve a lucidare bene il filo. L’angolo di levigatura, secondo le specifiche, è regolato per i prodotti della Global, ..ma credo che vada più o meno bene per gran parte dei coltelli a lama liscia.Ovviamente parliamo di una categoria che “non fa miracoli”: è utile se si usa abbastanza spesso (magari usando solo la mola più fine per mantenere il filo, e non consumare troppo la lama), senza aspettare che il coltello non taglia più.In ogni caso il risultato dipende molto anche da come viene utilizzato: i coltelli vanno passati cercando di eseguire un movimento uniforme, mantenendo bene l’angolazione perpendicolare all’affilatore, e applicando la giusta (lieve) pressione (a tale proposito c’è da dire che, considerando il prezzo, un foglietto con le istruzioni in più lingue potevano pure metterlo).
