I work in a healthcare environment and many of our male patients are with us for a while and as a result, need a good shave. I'd like to buy a razor (preferably inexpensive) and blades that I can use on them. It would have to be mild as some are on blood thinners and any cuts or nicks could be a problem. Also in order to use the razor on multiple patients it would need to be sanitize due to infection control. Any suggestions regarding razors, blades and disinfecting?
