Some razors are just awful! Which are in your murderers' row? I'm not going to include 99 cent razors form China! Here is my number one the Parker 99R Open Comb Butterfly. I find it aggressive yet inefficient; the worst combination of features. It's blade fussy and every blade I load it with produces a very uncomfortable and very inefficient shave. I dropped it from my rotation. What razors do you hate and why?
