Storing all your pens/pencils in a drawer is fine, long as you don't mind spending a few seconds digging each time you want to extract a particular one. In contrast I like to keep my sewing-machine-surgery tools broken out for easy grabbing, so I use a magnetic knife rack. The problem there is it will only hold my metal tools, not the plastic implements I also need to use.
Okay for metal stuff only
The simple bamboo units are filled with a series of rubber fins to keep the tools in place but separated, it can be oriented any which way, and embedded magnets let you stick metal things to the sides.
My only gripe is that the entire thing isn't transparent (yes, I'm still on that kick), which would allow me to see the business end of certain implements, but it appears this was designed for writing utensils and not tools.
In any case, van de Bospoort's had them on the Quirky store for 44 days, moved just under 600 units and clocked $1,400 for himself at press time. Sure he won't be buying a Porsche with it, but isn't it nice to earn a little extra cash just for coming up with a good idea? I loves me some Quirky.
