I gave my GF a non-adjustable DE to shave her legs with. Last week she was shaving & was getting all cut up. After a little investigation & fiddling, she discovers that the screw mechanism has loosened & the blade is more or less free-floating inside the head.
So double-check the tightness of the screw mechanism (or the setting if your DE is adjustable) before you start scraping away!
