Normally when you want to attach tools to walls for easy accessibility/viewability, you'll have to use a pegboard. The problem is that pegboards are ugly, and they're not always the right size for the tools you have. On the other hand, you could use these magnetic dots and always have exactly enough.

These tool dots lock into the walls with adhesives, so you don't have drill or screw holes to repair when you move out. The front is magnetic, and have a rubber bumper for a little bit of padding. The idea is to add more dots for heavier tools, but only enough so the tool doesn't fall, in order to make them as invisible as possible.

They're $12 for 12, which isn't a horrible price when you consider that most tools probably only need one dot.

Magnetic Dots Hold Your Tools On The Wall
