Knives are the unsung heroes of our kitchens. Whether you're slicing, dicing, chopping, or julienning, every flawlessly chopped vegetable, juicy steak, or slice of dessert can be served to perfection with the help of an effective knife.

Any home cook will tell you, good knives don’t come cheap, and even the highest quality options can lose their luster over time—especially when put through the extra wear and tear that comes with dishwashers and harsh detergents. That’s why many people protect their investments with a sharpening stone, which can help keep your knives working to perfection even years later.
