A knife guard covers the blade edge so it does not knock against other metal in a drawer, a bag or a knife roll. Most are plastic sleeves sold by blade length, and some have a felt lining. A guard only helps if it fits the knife, so measure the blade first.
The six guards below include single guards, multi-size sets and an adjustable case. Lengths, materials and linings come from each product’s listing page. We have not used these guards ourselves, and durability claims are the makers’ own.
