These are the sharpest production blades in the world. I'm not just making that statistic up. Ask anybody and everybody who has used a DE razor before and they will tell you "Feather." You get 10 blades for about 6 bucks, it depends where you shop. Once you test them out and if you like them, you can buy bulk lots where you get 50 blades for about 25 dollars. Keep in mind that these are "Double Edged" blades. So essentially you are getting 2x the blade. I usually keep a blade for 10 to 15 shaves.The first 5 or 6 shaves it cuts extremely well. After 10 shaves you start to get a little pull. This "pull" is comparable to the store bought high end cartridge razors straight out of the box too.
