SCOTTCHEN Diamond Whetstone Knife Sharpener | 3 Sides Grit Coarse 150|Grit Medium 325| Extra Fine 1200|TRI-HONE Sharpening Stones

This is a large diamond stone (2 3/4" x 8" cutting surface). My last natural stone was about half the size and was a pain to sharpen longer knives with. It has a nice cradle (5 1/2" x 14") that does not rock or slide on the counter. Really like that it's three sided. The 150 grit really works great to get those really dull knives an edge fast and the 1200 grit polishes super sharp. I dinged it a star because it was supposed to come with an angle blade guide, which would be nice when you first start until muscle memory kicks in. Not sure how long the diamond surface will last as opposed to a natural stone but I can say that I've sharpened about 30 dull knives and about twenty five of those were basically useless except for warm butter. My neighbor borrowed and had it for a couple of days so I assume he did more than a few as well and I see no traces of any wear on any of the grits by keeping it wet.

This thing works awesome,Just wish it had grit between 325# anf 1200#

It doesn’t come with the plastic degree The stone was loose in the plastic wrapper and the wrapper was stuck too the sticky side of where the stone goesBut seems to stay steady while trying to sharpen your knife
