I found a wooden test tube rack from a scientific supply company. It has 12 holes to store razors. I cut off the test tube drying pegs with a flush cut saw and put another couple of coats of polyurethane over the whole thing.
Only the shorter razors will fit (Super Speeds, Techs, some GEMs) because of the height of the rack. Fat Boys, Slims and some other razors are too long for this rack. I have an old pipe rack that I use to store the longer razors.
Not the prettiest solution, but it works for me. I would like to see any other storage or display ideas anyone else uses.
