This Eva Solo knife magnet set provides outstanding versatility and more flexibility than traditional knife sets. These four oversized circular magnets are encased in stainless steel with non-slip rubber fronts and adhere powerfully to any metallic surface offering ease of placement almost anywhere in the kitchen. This set even comes wih special wall fittings. Just screw the fittings onto the wall with the enclosed screws and mount the knife magnets on the fittings – magnetism holds them in place. Each magnet can hold up to two knives simultaneously, depending on the dimensions of the knife. One magnet can hold your largest cook's knives or even your cleaver while providing function, as well as style. The knife magnets are easy to clean – but are not dishwasher safe. Always remember to place the knife magnets out of reach of children. Each magnet is 2-7/8" in diameter. 4 magnets to a set.
