I'm a blade-a-holic, so I've tried a bunch of em on my way towards the top which has left me with a stash of junkers. I have coaxed at least 3 other friends into DE shaving in the past year and I purposely give them Merkurs and other low end blades to start on. That helps me get rid of my stash while helping them appreciate a good blade when they find it. They are happier this way. So, sucky blades do serve a purpose.
