I'm am not one for writing reveiws, but this little sharpener is the thing to have. I have used other stones,but they are kinda big and heavy. This one is narrow, short and lite weight. 2 or 3 swipes on the diamond side, couple more on the ceramic side, and your knife is pretty dam sharp. I am going to keep this one for my pack and buy another one for just around the house. Hope this helps in your decsion making. It's worth the money.
