“I own this knife sharpener. It really is worth the money. An excellent product that is easy to use IF you follow the instructions.”
“I'm unimpressed with the third stage on this”
“Never again, though, will I use an electric grinder like the one recommended here.”
“I'm really pleased with this! It works like a charm”
“I bought the Trizor XV and I have to say, the printed instructions that come with it are overly long and complicated.”
“I have the dual angle version (15/20) of this Chef's Choice sharpener but stopped using it because it was too easy or me to remove much metal”
“I have the Chef's Choice, but really, the one I have used the most over the years is the Chantry knife sharpener”
“It can recover damaged knives, and eliminates the need for a honing steel (a task I despise). A few strokes through it and you are professionally sharp again. Totally worth it. But it is pricey. The two-stage version (same link) is half the price but can't fix a damaged edge.”
“Sold mine a year ago. I now use an 60$ diamond stone dry.”
“it takes a ton of material off. Look at the scratch pattern up close and it is scary”
“I own this sharpener and does a very good job. But...”
“it really does do a great job otherwise”
“This one isn’t great. Get the Tormek with the diamond wheels, so worth it.”
“It does about 95% as good a job as a stone in just a few minutes. But if you bought great knives, you will find the entire blade marred.”
“I just sharpened 5 different knives using YOUR notes and it worked perfectly.”
“I can confirm that the Chef's Choice sharpeners take off very little metal.”
“I have one, and I don't like it.”
“I tried painter's tape to prevent the scratches but it still scratches the knife a little bit.”
“I've never been entirely satisfied with the edge”
“My final advice this sharpener is an expensive brick or stone don't waste your money.”
“It certainy does a good enough job for me as a home cook.”
“I own both a Chef'sChoice 15/XV + a few whetstones. If used properly, the Chef'sChoice is roughly equivalent to using the whetstone with at least a medium+ amount of skill. It produces a narrower angled blade (15 degrees versus 20), but this is fine if you are fine with the difference, if not, Chef'sChoice makes a US version of the same sharpener as well. Th”
“It was a lot of money to pay for something I've used only once in 10 years, but no regrets”
“I would never run any knife I cared about through any of these electric sharpeners.”
