Have been shaving with merkur 34c for two weeks, every shave I've had with it ended in redness,spots,bleeding ..... Was about to throw a hissy fit ,when last night I read the beginners guide in the forum ....Just finished shaving using only a two shave pass,but I spent more time preparing my beard,and only using the lightest of pressure,just the weight of the razor..No blood,no bumps,no fiery neck,WOW .......
