The 440 Mino Sharp Plus knife sharpener is slightly larger and more sturdy in construction than the 220 MinoSharp. The 440 is intended for heavier use. Like the 220, the 440 has two sharpening slots which are pre-set so you can get a perfect edge on your Japanese knives. The separate slots feature a coarse grit and medium grit wheel for a truly fine edge. Each wheel rotates over a small water reservoir to keep the blade clean and cool while sharpening.

I purchased this sharpener to use with the Global knife I purchased at the same time but of course after less than a week of use their has been no need to sharpen it yet. I used this sharpener on a cheap kitchen knife my roommate had and we were amazed at the edge it put on the crappy knife. It's ease of use is great and I would recommend it to anyone.
