ever since I got a straight razor shave at a barber shop I've wanted to shave that way regularly... the startup cost can be pretty high, but taken care of the razor will last a lifetime, no buying expensive refills...
after the barber shaved me with the straight razor I felt smoother then ever and had almost no irritation which is usually a big problem with me
unless Its a special occasion I just run my trimmer over without the plastic adjustment on it, and basically just have perma stubble, if your girlfriend doesnt mind the stubble just go with that.
