10 Best Knife Guards 2026 in the United States

The Mercer Culinary Knife Guard is made from sturdy polystyrene, providing strong durability and good protection for knife blades. Its size of 8 by 2 inches fits knives with blade lengths of 7 to 8 inches, making it suitable for popular kitchen knives like chef's knives, santoku, and cleavers. This means it covers most medium-sized knives comfortably, helping keep blades sharp and safe during storage or transport.

The design fully encloses the blade, which enhances safety and prevents damage. Cleaning is easy since it’s dishwasher safe, though hand washing with mild soap is recommended to maintain longevity. It’s lightweight and simple to use, requiring no assembly. Its hard plastic construction might not offer much flexibility if your knife is slightly larger or smaller than the specified size range, and although tough, polystyrene can crack if dropped or handled roughly.

This guard is suitable for both professional chefs and home cooks who want to protect their valuable knives without fuss. For those seeking a reliable, easy-to-care-for guard specifically for 7 to 8 inch blades, this Mercer model represents a solid choice.

The Asaya Professional Knife Edge Guards are crafted from durable ABS plastic, making them a strong and non-toxic choice for protecting your knives. They come in a set of six different sizes, which should cover most of the common kitchen knives, such as pairing, utility, santoku, fillet, bread, and chef knives. The universal design with an angled opening allows for a good fit on both slanted and straight knife handles, enhancing their versatility.

The textured surface provides extra grip to prevent slipping, making them safer to use when sliding knives in and out. However, these knife guards are not dishwasher safe, which means you will need to hand wash them to maintain their cleanliness. While their BPA-free and food-safe properties are commendable, some users might find the black color and plain blade edge a bit basic.

Despite being injection molded, they are relatively lightweight at 8 ounces, which might be a plus for ease of handling. If you need durable, reliable knife guards and don't mind the extra care required for cleaning, the Asaya Knife Edge Guards could be a good fit for your kitchen.

The Mercer 11" x 2" Knife Guard M33118P is a solid choice for protecting your kitchen knives. Made from sturdy polystyrene, it offers impressive durability, ensuring your knives remain sharp and safe during storage and transport. The one-piece construction is a standout feature, suggesting it will hold up well over time without breaking or cracking. Measuring 11 x 2 inches, it is designed to fit knives ranging from 10-11 inches, making it versatile for various types such as Gyuto, salmon slicers, and sujihiki knives.

This makes it a good option for both professional chefs and home cooking enthusiasts who use high-quality knives regularly. The guard is also straightforward to clean. It can be hand washed with warm water and mild soap or even placed in the dishwasher, adding to its convenience. However, some users might prefer hand washing to maximize longevity, as suggested by the manufacturer.

One potential drawback is that the polystyrene material, while durable, might not offer the same premium feel as higher-end materials. Additionally, it only comes in one color option, which might not appeal to those looking for a more personalized look. Despite these minor cons, the knife guard's excellent build quality and ease of use make it a top choice for anyone looking to protect their knives effectively.
