Check out this picture.
I was at an antique store in Akron, OH a couple weeks back and saw this massive box of Gillette razors, which all appear to be some flavor of the Tech.
Turns out they all came from a medical care facility, but the interesting thing is that they needed a key in order to replace the blade. The guy at the store told me they did this so the patients couldn't take out the blades and cut themselves.
