Kitchen knives cut and prepare food and ingredients. Kitchen knife sets include basic knives used for common cutting applications such as chopping and slicing. Cutting boards are dedicated cutting surfaces that protect surfaces from scuffs, cuts, scrapes, and scratches. Cutting board racks hold and organize boards when not in use. Knife steels and sharpeners hone blade edges. Sharp blades prolong the lifespan of kitchen knives and reduce the chance of personal injury when processing ingredients. Knife racks, guards, and cases prevent blades from dulling prematurely. Kitchen shears are used for various kitchen applications such as cutting twine, processing poultry, and trimming bundles of herbs.
