What is a chef's knife?
A chef's knife is a long, straight-bladed knife used to chop, slice and dice vegetables. The blade of a chef's knife is usually between 5 and 12 inches long, though it can be as short as 3 inches or as long as 18 inches. The width of the blade ranges from 1/4 inch to 1 inch. A quality chef's knife will have a quality bolster. The bolster is the part that sits where the blade meets the handle. The bolster is the strengthening element for the entire knife and it also prevents food from slipping back onto your hand as you slice it.
Why use a quality chef's knife?
Chef's knives are great for chopping, dicing and mincing foods because they're so versatile: they're relatively easy to manoeuvre in tight spaces and come with wide blades that make quick work of cutting up large amounts of ingredients. A quality chef's knife will feel balanced in your hand when you pick it up; it won't be too heavy or too light. It should also feel comfortable when you grip the handle; if it doesn't fit well, you may want to try another option before settling on an uncomfortable knife that won't perform well while cooking on the job.
