This is my stash. I reckon I have enough blades. But having enough and having too many are two seperate things. Especially since yesterdays favourites are often replaced for something better tomorrow. I don't know how many blades I have, but I reckon it is around 12-1300. About half of these will probably see very little use.
I shave three to four times a week. Then depending on the blade; I can get at least 3 to 5 shaves from each blade(quality blades). I'm not shaving past 100 years old, so I need less than 2600 blades. Now this all said, when I use Polsilvers I can get ~15 shaves from a blade and that changes the count all together.
