A:AnswerThe Presto® EverSharp® electric knife sharpener will sharpen knives of alloy, carbon, or stainless steel. It is designed to sharpen kitchen knives and most sporting knives. Do not attempt to sharpen scissors, serrated electric knives, pizza cutters or any blade that does not fit freely in the blade guides. We do recommend asking your knife manufacturer if sharpening their knives on your own is acceptable. Some knife companies have their own warranty. If there are any questions or concerns, please reach out to Presto Customer Service Department Monday-Friday 8:00 am - 4:00 pm Central Time by phone 1-800-877-0441 or e-mail [email protected] We are here to help.
A:AnswerIt says yes but it’ll slowly strip the serrated part until one day it’ll just be a knife. So personally I wouldn’t rely on it for that. I have sharpened a serrated knife but it’s just as I said.
