A cook's knife is their most important tool and Eugene Ong has been obsessed with cutlery for a long time. As a chef, he came to appreciate the necessity of a perfect edge - from there, knife sharpening became a full-time obsession. For 15 years, Eugene has run KNIFE in Toronto, teaching young cooks how to hand-sharpen their gear as well as passing on the lessons of discipline required to maintain blades in peak condition. Now he also drives the Knife Truck to various towns in Ontario to bring his hand-sharpening skills to a broader audience.
