I used the included double sided adhesive tape to mount them above my backsplash to hold 4 of my high dollar chefs knives. Used 4 magnets for 4 knives and it works fine. Actually bought to put inside a magnetic knife bar I'm building. Just been lazy. But they will work great, because single magnets are already holding them to my wall.
