So, what you're saying is that there are some Gillette Psycho keys lying somewhere at the bottom of the Gulf of Mexico?The short answer is to many. I have 20 Gillette Psycho Razors and 14 Keys. I also have 4 Grafco razors and 1 unbranded razor. When I bought one of the lots from a former prison employee He included a full box of razor blades they used at the prison. A few years back I had a local machine shop make me several replacement keys and I some of those still.
In 2016 we went thru the Great Flood in Baton Rouge, LA. Me and my family made it out OK but I did loose several razors and some of the thing I lost where some Gillette keys and razors.
Let me just slip this scuba gear on real quick...
