I'm using the Feather Proguard Blade in my Shavette since yesterday and really like how smooth it shaves. I read an angry review of a father who tried to teach his son to shave with a shavette and this blade. He claims that his son sliced up his face. I can't imagine how someone could injure himself with this blade. Does someone know if this is possible? For me it feels like absolutely nothing bad can happen, no matter how bad the technique is. What do you think?
