Not functioning properly

Disappointed The various stages don’t seem to engage the blades consistently or at all. On the right side of stage 3 there seems to be no sharpening in first 2/3 of the blade and then blade suddenly drops down and sharpens the final 1/3 (tip) of the blade. Tried chat but it is robot. Chat and website only want video and proof of purchase rather than telling how to resolve. Told me to return so that is what I am doing

Sharpened knife cut through lime like butter
on May 4, 2025
Posted by: lynchewbie
I never want to use the knives from my knife block for small jobs and have these cheapy go-to knives I use all the time and love. I’ll replace them when they go dull, so I have a drawer full of unused knives. I got this sharpener as a gift about a month ago and decided to test it out on one of the dull, Asian paring knives I have. After pulling the knife through both sides of the first slot, my knife was able to cut through a lime like butter! Love how easy it was to use too.
I would recommend this to a friend!

Trust your knives to the 1520.

Sharpens precisely, quietly and consistently. To use correctly takes a bit of practice but is worth it. Read the directions!

Was always afraid of an electric knife sharpener…

I have always had fairly sharp knives, but not really sharp knives. I’ve tried a lot of different sharpeners and I’ve had mixed results and have always been very leery of electric ones since I’ve heard all the horror stories about people grinding their knives away to nothing.
However, after reading the way that cooks illustrated in America’s test kitchen raved about the chef’s choice. I decided to give a 1520 a try.
The learning curve exists, but it is not steep. The results are absolutely amazing! No question that I have waited too long to buy one of these and will recommend it to everyone. I know that needs sharper knives!
I would recommend this to a friend!

My brother bought this sharpener for me as a surprise gift. We had been talking about the same one he has. It did a fine job of the much needed sharpening on all my knives, even the serrated ones.

Sharpening wheels not spinning (?)

Got this as a gift, read the instructions, but when I turn on the power switch it makes a hum, but the sharpening wheels do not move. Seems defective. Watched a video of someone using the same sharpener and yea, his works perfectly. Maybe I got a bad one.
I'm going to call to return.
No, I would not recommend this to a friend.

Great for sharpening non fineness cheap knives .
I have VG 10 blade knives that the metal is to soft for this grinder
After sharpening it then polishing on a 8000 grit stone the knife ,it still was micro rough
Not recommend for high end knives .
I would recommend this to a friend!
