Works surprisingly well
I have had MinoSharp Water Knife Sharpener, Gray/Black for 2 years and it works very well for me - surprisingly, in that I've never before had great luck with DIY "sharpeners".
It brings back the sharpness of my large Global chef's knife very well. Also, it works on some of my other knives (such as a low-cost Oxo that has a thin blade) - even though these other knives do not have the same angle as the Global. On my more traditional knives with thicker blades (and which I had had professionally reground), the results are only OK, but still helpful. (Besides actual food cutting, I judge my results using the "paper test".)
All this said, I do run the blades through the rollers maybe 3X the number of times recommended in the instructions in order ... Read More
Yoshikin makes two similar sharpeners...
I'm posting this as a comment, not as a review. Yoshikin makes two sharpeners that look almost identical, model numbers GS-220 and GS-440. The model where the plastic covering of the ceramic wheels extends to the sharpener's handle is the GS-440. The model I posted this comment for is the GS-220. The 440 goes for ~$50 whereas the 220 goes for ~$35. To be honest, I don't know how the two differ technically. Yoshikin claims the 440 is a heavy duty version of the 220 and is designed to work on German knives as well as Global knives (the 220 is only recommended for Global knives).
Wonderful, easy to use
This is the perfect sharpening device for people who own Global knives. It's extremely easy to use. You fill it with water, run the knife through the coarse dial a few times (making sure not to apply too much pressure to the knife), then run it through the fine dial a few times. Next thing you know, you have a knife that is good as new. My Global knives have gone from dull and giving me a lot of trouble cutting through vegetables to being able to just set the knife on top of a vegetable and let gravity do its work to cut through. All it took was a use of the minosharp in between.
Classy Chef
Well, I purchased MinoSharp Water Knife Sharpener, Gray/Black at the same time I ordered the Global knife since it seemed to be recommended. It's just ok. Nothing to rave about. In fact, I like my little fish-shaped one I got from Home Depot for just $10 much better.
Works Well for my Global Chef's Knife
After emailing several places, I found this is the correct sharpener for my Global Chef's knife. I was concerned about keeping the edge at the same angle as it was originally. The clear plastic tray cover lifts off easily so water can be added to the tray. Simply roll the knife through several times and the edge is back to original condition. I recommend this sharpener to keep your knife like new.
