Since there’s basically no end to the different things you can put in your omelet—meats, vegetables, herbs, or otherwise—you’ll want a good chef’s knife or set of chopping knives. A good chef’s knife will be sharp right out of the box. If it isn’t, send it back and buy another one. Things to consider when choosing a chef’s knife include weight, balance, size, grip material, and grip texture. An 8-inch chef’s knife is the most popular size for amateur cooks. Just remember that chopping is always easier with a very sharp knife, so keep a sharpener around to put a clean, sharp edge on your knife before every other use or so.
