This is an exceptional item. I have used a few different knife storage solutions over 40+ years. This is a good design and easy to install. They provide a template for your choice of screw/anchor mounting or included tape to mount on a smooth surface. I suggest the anchor. Tools: Carpenter's level, pencil, drill and Phillip's head screwdriver. I think this will stay on the wall without becoming wobbly like the magnetic bars which tend to become wobbly over time. This will not receive that sort of stress from pulling knives off of it. Brushes hold the knives in place and only a light vertical touch is needed to remove a knife.
