I hate shaving.
With my current job in the catering business I'm not allowed to have a beard but they are okay with a moustache. I keep that trimmed with my beard trimmer.
When I was working other jobs or between jobs I just don't shave.
I use a Mach 3 razor that I got in the mail and rarely change the blade because they are pretty damn expensive. I always end up with a TON of disposable razors on Christmas and use those when I have them.
