Chef'sChoice Electric Knife Sharpeners Diamond Hone with 100-Percent Diamond Abrasives and Precision Angle Guides with XV Technology for 15-Degree Straight-Edge and Serrated Knives, 2-Stage, Black

Bought this sharpener for my new Shun knives (Japanese, 15 degree edge). Used it to put a 15 degree edges on my "20 degree edge Henckels" set also. It takes some effort to convert a 20 degree edge to a 15 degree edge.To convert, you're going to have to grind away more of the edge than merely sharpening. (Doesn't actually grind the sharpest part of the edge, but rather grinds down some of the metal "above" the edge so that it conforms to the 15 degree template.) There are instructions for this included with the sharpener, but here's a tip on how to make that conversion a bit easier.You're likely to have to pull the blade through the sharpening side 25-30 times on each side to "reshape" the edge. Of course you can alternate left-right, left-right, 30 times. After doing that on my first couple of blades, I modified the procedure a bit.1. Grind only one side of the blade maybe 15 times. Check for a "burr edge" as described in the instructions. 15 times likely not enough to form the burr, so grind 5-10 more times. KEEP COUNT OF THE TOTAL NUMBER OF PASSES. Once you feel the burr, grind the other side of the blade. The burr may disappear after only a pull or two, but the 2nd side of the blade won't be properly shaped yet.2. Grind the 2nd side of the blade the same number of pulls you ground on the 1st side. That will make the edge more-or-less perfectly symmetrical.3. Then make 2-3 passes, alternating left-right just to be sure it's even on both sides.4. Then make several passes on the "polishing" side of the sharpener to finish.My Henckels Chef's knife took the greatest number of passes through the sharpener because it's the thickest blade... more needed to be ground down above the cutting edge, but worth the effort.

The media could not be loaded. Maintaining sharpness becomes very easy with this sharpener, if used correctly. When you introduce your dull knife to this easy to use sharpener you may need a few runs to adjust to this machines angle, however once achieved you can maintain sharpness with just a few runs. We have been using this sharpenerWe have been using this sharpener for over 6 months and thus far we have no complaints.Pros:- plug and play, no setup required- small- easy to use & maintainCons- not suitable for knives 14” + in length- not suitable for knives 5mm + in upper blade thicknessWe can highly recommend this device to anyone requiring easy knife maintenance.

It’s ok

Easy to use , he lov

I bought this sharpener because I wanted razor edges on my knives for work. I have used on all my home knives, and on all my work knives.My kitchen is very prep heavy and using a sharp knife makes all the difference. I have found that no pull through manual works the way I like, and I'm no good with a stone, but this put an edge on my hardest Damascus steel knife and all the knives with ease.I had to put more work on the hard steel ones but it was worth it. German steel worked well at this angle too.

Bought this on America's Test Kitchens recommendation. It works super well and is really easy. Knives are sharpened beautifully

I wanted so badly to finally get a tool that would sharpen my knives with that razor edge we're all looking for. I read the instructions thoroughly, did exactly as was directed, and ran several of my knives through the process. What I got was slightly better than they were, but not what they said would be a razor edge. After testing on a couple older, less used knives it did improve their edge somewhat. Running my daily driver through it made no difference whatsoever. When I was done I tried slicing a tomato with no luck. I guess it's back to the whetstone and elbow grease for now. I will say that it looked like the box had been opened, so it's possible that I got a returned item? Returned for a refund.

THIS IS OUR SECOND CHEF'S CHOICE KIFE SHARPENER. THE FIRST, VERY SIMILAR, "NEARLY" IDENTICAL, TO THIS MODEL 315XV, WITH VERY FEW STROKES, WOULD TURN A KITCHEN KNIFE, A HUNTING KNIFE, A POCKET KNIFE, INTO A "R A Z O R." THIS ONE CAN'T EVEN SPELL 'RAZOR,' AND ONLY WITH SOME EFFORT, WITH SHARPEN SOMEWHAT. WHAT HAPPENED ? ?
