I suspect that there are more than a few people with complete high end kits with fancy razors, brushes and strops sitting in a drawer somewhere, that wil never be used and that might be what keeps these places in business.

I see the same thing with flyfishing. I've been an avid flyfisher for quite a while now and every season I see guys sporting brand new rods, reels, waders, boots and assorted paraphanelia that must total in the thousands. Rarely do I see them more than once, and I'm on the stream a lot!
