I am fairly new to DE shaving, and finally came to these in my sampler pack I got for fathers day. Got to say, these blades are SHARP! Shaved today after two days of no shaving, the blades already had two shaves on them, so I wasn't expecting a very good shave, just to get it done. After just 2 quick passes, I have a smooth shave with no nicks and no irritation. No need for a beginner to beware in my case. They work great for me.
