As stated above, you are probably having technique issues. There is a big difference between a disposable razor (cartridge) and a DE/Str8. I am a little concerned with possibly the pressure you are using. The blades on these (DE/Str8) should barely touch your skin with hardly any pressure. That is where a benefit will be for you with either one of these. The key is the difference in pressure, typically we scrape our face with a Cartridge, DE/Str8 you barley touch your face. Good Luck
