Global magnetic blade guards are designed to secure your knives safely and conveniently. When you dont have a block to store knives, or if you prefer to store knives in a chef's case or drawer, these guards offer the perfect solution to keep your knives safe and sharp. Each guard is made of a soft touch and flexible plastic material with a magnetic strip inside to hold the knife in place. The guard has a hinged design to make it easy to insert and take out your knife. The guards come in 3 sizes, small, medium and large. Typically a size 1 will fit a GSF knive, size 2 as GS knife and the size 3 a G range knife. The guards have Global branding on the outside but can be used for any brand of knife.
