Hardshell sunglass casses make great razor cases for travelling. It also really confuses people.

+1 to tekbow....toothbrushes as guitar/fret cleaners.

I also have a beautiful african djembe on my patio that had a cracked skin. So I took off the skin, leveled the bottom and stained the whole thing. Got a stained glass shop to cut a piece of 1/4" clear glass for me (round), and now I have a great looking beer and cigar table out there.
