Use pegboard & show off your collection of beautifully hand-crafted tools (I have found mine from many a port, nook & cranny) & other shapes like a fly swat made from braided leather & horsehair, as a form of art.
This reminds me of the hardware & woodworking stores on Straight Street, or A Street called Straight, in Damascus (or your grandfathers old shed).
I am addicted at the moment. In our new office it holds a plethora of tools and interesting odds n' ends. Not just tools.
I also used as a bit of a folly at restaurant/bar, MsG's.
