Toss, the Kyocera electric sharpener
| The Kyocera diamond hone electric knife sharpener is powered by four AA batteries. They don't have the power needed. |

The battery door of the Kyocera diamond electric knife sharpener notes that it takes four alkaline batteries. I don't use disposable batteries, so I put in four rechargeable NiMH batteries. That battery chemistry has a full-charge voltage of 1.2V. An alkaline battery has a full-charge voltage of 1.5V.
So maybe with four alkaline batteries and an operating voltage of 6 volts, this sharpener might have enough power to not keep stalling as I gently ran the blade though. The thing is, both battery systems have a discharged voltage of 0.9 V. So that means as soon as the alkaline cells get a little use, they will be just as lame as the rechargeable ones I show in the video. It is just too hard to keep the motor turning. |
Note that when the sharpener stalls out, it is with a very light pressure. Even the weight of the knife will cause it to stall. The diamond wheels are rubber-mounted, so they should allow at least the most modest pressure needed to get a good edge. Going slow, going fast, nothing made a difference. I just don't have the motor coordination to keep pulling up on the knife as it barely touches the diamond wheel.
My next electric sharpener will plug into the wall. I am looking at Presto and Chef's Choice sharpeners. I will do a video about those soon.
