I recently threw away my multi-blade plastic cartridge razor and bought a double edged razor (my face still thanks me and so does my wallet). In the process of learning how to shave with the new razor I looked on some forums for tips and advice. What I did find were a few threads about when double edged razor blades will be discontinued. A lot of worry on the threads as most people now use plastic cartridge razors so how long can traditional blades hold on? Perhaps it's human nature to worry about the unknown, but at least film photographers are not alone.
