This inexpensive hand-held knife sharpener is quite amazing. It’s 2-stage sharpening process brings dull knives back to life quickly and easily. A few pulls through the coarse, carbide side will set the edge. Followed by a few pulls through the fine ceramic side to finish the edge. I generally use the fine side of the sharpener most and only use the coarse side when a knife becomes very dull. Remember to rinse the knife after sharpening. I paid about twenty bucks for this and it’s been terrific.
