Global Ceramic Pull-Through Water Knife Sharpener G-91/BW, 2 Stage Knife Sharpener Coarse & Fine Wheels for Sharpening Knives, Black, Sharp Kitchen Knife Edge Maintenance, Made in Japan

Ok, Japanese ceramic whetstones might produce a better result (as long as you have the time & skills to use them - what a hassle). This high quality knife sharpener is a great tool for maintaining the sharpness and effectiveness of our knives. Its ease of use, consistent sharpening angle, durable construction, and compact size, make it a perfect addition to our kitchen.

I have had this a couple of years now, did my monthly round of sharpening this morning and was again impressed by how easy this is to use. It works well on my fancy Global knives, and even the cheap ones are improved. Strongly recommend, which is more than I can say for the other half dozen sharpener I have tried!

Quite good got all my knives sharpened. I use it once a week.

I have just finished sharpening my Global knives and they are back to their razor sharp best. Really easy to use but the knives had to have a few more runs across both stones as they were pretty blunt.........for global knives that is. Would not hesitate to recommend this sharpener

I have a set of global knives which over the years have lost their keen sharpness. I’ve tried lots of different sharpeners and this one seems to be the most effective. After carefully following the simple instruction my knives feel sharper and cut beautifully again.

I bought this as a Which Best Buy recommendation. Its easy to use for left and right handers (important in our house) and has improved our knives. Previously we used a different sharpener design but that left blades "ragged". It promises to be a good investment

I have tried to learn from YouTube several times how to sharpen a Global knife with a wet stone but never had great success. I had a similar knife sharpener before but was never happy with the results. This product does the work! I don't know if it is the quality of the stones inside or the angle which is unique to Japanese kitchen knives, but it sharpens the knives really easily and they pass all the tests - tomato, grasp, paper, and so on :-)

It lasted 10 months

This is the third time I have purchased this sharpener since 2013. They last a long time but you eventually need a new one. Very easy and quick to use. Can have a long sharpening session or bring it out for a quick touch up. Easy to keep my expensive kitchen and steak knives razor sharp. My Uncle Bobby always said, “if you want people to think the steak is tender, hive them a sharp knife”. Very stable in the kitchen counter and the handle keeps your fingers out of the action. There is a place to put water that keeps the stones from getting hot and damaging the steel.

Comodo per via dell’ impugnatura e del basso rischio di taglio e ferimento durante la procedura. Purtroppo non affila più di tanto precisamente e rifinito il filo del coltello

Si saca filo pero los cuchillos lo pierden de inmediato.

Works well and convenient and simple to use. It's not a fine stone but doesn't take big chunks of steel off like some other crude metal sharpeners either. With fine sharpening stones I used to take 20min per knife at least. And because not as convenient I would only get around to it once every 2 months, which by then the knife is blunt. With this one I run it through 15 sec on fine before cooking and it keeps the knife sharp all the time. I dunno if I would use it if I had 500 dollar knife .. but for say any vg10 type knife in home kitchen it's perfectly fine.

No real surprise that this sharpener is awesome for my Global knives since it is made or at least approved by Global. It does an excellent job with my g-48 and g-80.
