Bamboo is a very eco friendly wood that grows to a harvestable height of 60 feet in just 3-5 years (compared to other hardwood like Oak that takes at least 40 years). The extra thickness of 1 inch makes it easy to pull and put the knife back to the rack. The continuous magnet allows any metal objects to be placed anywhere on the bar. Easy installation; simply put two drywall anchors (mounting anchors included) on the wall and hang the bar. It can be used in the kitchen, workshop, office, garage, etc. It's a unique great gift for anyone.
