Extra-Strong Neodymium Core: Powerful neodymium magnets keep knives in place — strong enough that even heavier chef's knives stay put, but never so strong they're hard to remove. The right strength, by design. No Weak Spots: A close-packed array of neodymium magnets delivers continuous magnetic strength across the full length of the rack. Knives hold from end to end. Two Ways to Install: Choose the supplied 3M adhesive strip for a no-drilling install, or use the supplied drilling template, wall plugs and screws for a permanent fix. Both methods, in every box. Room for Your Everyday Set: Comfortably holds 5 working knives — paring, utility, chef, santoku, bread — with plenty of room for more. The 40 cm size suits a typical home kitchen. 100% Solid Bamboo: Sealed with a satin finish that resists everyday kitchen wear and wipes clean with a damp cloth. Bamboo's natural light tone suits any kitchen aesthetic.
