Yeah DT, I used to have a couple of them. I kept one strapped to the handle of my tool cart, worked great for keepin the wrenches/sockets I had on the current job together. However it will NOT support a socket still connected to the airgun. I've seen them in Kitchens and they work well. However if they're not coated or don't use some design to keep the blades off the magnet they can show wear. Not a big deal with most of the knives I see here, but of some concern if displaying anything collectible.
