Gentlemen, if you ever find yourself stranded on Thanksgiving Day in the estrogen-soaked suburbs with no heavy industry, metal works, machine shops, hardware stores or even a half-decent Shed nearby, and you are stuck with a dull carving knife that wouldn't cut soft butter on a warm day, then here is something you can do:
Use the bottom unglazed rim of a coffee mug to sharpen the knife. Ten or twenty strokes each side with firm pressure and a steady hand should do it. Ceramic is harder than steel, and unglazed it has just enough roughness to work in an emergency.
However, make sure you are well out of sight and even earshot of any WAGs. Because nothing you can say will convince them that you are NOT somehow destroying the mug, the knife, your health, your credit rating, your children's futures, and any chance they may have had of getting into a good college someday. They will not understand this unauthorized use of kitchenware.
So we'll just keep this our little secret, shall we.
