This product sharpens knives very well, even the most damaged!
The diamond face is rarely used when the edge of the blade is very damaged. Otherwise the ceramic face made his job very well, and wears very slowly.
For sharpening a razor, you will probably need other finer stones as the stones of Arkansas or Japan.
But frankly the razor sharpening is not necessary! Sharpening that provides this product is great for all that demand the kitchen. On the other hand, the razor sharpening, will require a more regular sharpening, since the edge of the blade is thinner and will spoil faster.
I could even refine cutting a paring opinel new with this stone, which was already very sharp at the base ...
Very good product to recommend!
Info. 1: Watch the diamond face of gold, use the blade, and removes material. It is to be used only if the edge of the blade is no more. Otherwise use ceramic face!
Info. 2: To verify that your knife is sharpened dice, put the knife to light: the parts that glow are the parts of the knife that cut more. The edge of the blade crashed, damaged ... etc. This helps to know when to réaiguiser his knives.
Info. 3: After your knives sharpened with this product, pass the knife on a piece of leather stretched in the opposite direction to the cutting direction. This will further refine sharpening removing all infinitely small fragments that remain hanging on the edge of the blade. It's like what we see in Westerns among barbers.
Info. 4: Once you have finished sharpening knives, rub the gray side (ceramic side) with a damp paper towel to removed the fine gray powder that remained on the stone! Otherwise you'll end up with dirty hands, or you salirez other things ...
Info. 5: To check if the knife cuts well, you can use the test sheet of paper, or tomato. If it crashes is that the knife is sharpened badly. This must be decided. You can also rub the knife in the direction perpendicular to the cutting direction on the apple of your hand to feel the edge. If it slips, and you hear / do not feel the friction of the blade is that the knife is not sharp. Note that the office which I have refined with the stone Opinel has better friction before refining the second I did not refined ... But in light I could see that the refining provides a perfect blade wire without brilliant part, or damaged. So use both methods to see if the knife is sharp.
Info. 6: On Laguiole knives type, or the point of the blade is not straight as an Opinel, you must make a circular movement of the wrist, to sharpen the tip, otherwise it mocks the face of the knife to the parties that will be then in contact with the blade ...
Tip 1: Do not cut your food on ceramics, it wears knives ... they lose their ability to cut quickly. Use a cutting board.
Tip 2: Watch videos on YouTube / Dailymotion for how to sharpen a knife. There is a simple movement to learn or you tilt the blade of a little less than 45 ° and preferably make a circular movement in the direction of the cut.
