Bon Appétit’s Brad Leone is back for episode 64 of It’s Alive, and this time he’s showing you how to sharpen a knife. Brad teaches you how to use a sharpening whetstone and transform your dull knife into a barbershop-ready blade (do not try at home). Tips from an old friend (Bob Kramer!), Gaby tries cosplay, and Chris settles the score: Rambo stropped.
