“It’s portable and easy to use. It requires no special skills. You just lightly run it along the blade. It’s a sharpener for dummies!”
My in-house designated-critic, wife Linda, tried out the AnySharp Edge (anysharp.com), a tool and knife sharpener, that the manufacturer sent me, and was ecstatic about it. “It’s genius,” she told me, “so easy to use that I’ll use it a lot.”
That probably tells you all you need to know about this sharpener. But I will say a bit more.
