These hanging magnets are the most flexible wall storage system I've found, namely because they fit, making it easy to add extra tools or completely replace chisels with screwdrivers, for example. In addition, the installation is done with two screws - you can hardly complain about that. For the first time in years, my entire collection of allen wrenches is organized for easy access. For screwdrivers, you'll probably need to use two parallel bars, as the round shank of a screwdriver doesn't lock well in a vertical position - you'll need another anchor to keep it vertical with the handle facing up, or it'll roll off to the side of the magnet . You can put them upside down with the handle down, but that looks a bit odd, and to make the most of it it's nice to have the handles up and down a bit - or offset, and it helps to have it two do it.
