I like to collect. So right now I have too many (30+). I would say that 10 of the razors I try to put in my shave rotation. Which for me averages 3 shaves per week.The others are on display for me to enjoy and for my wife to make fun of. Also, I have shaved at least 2 times with all of them. I have pretty much slowed down considerably on accquring new razors.
