I'm just about to replenish my Feather de blades and can't help noticing a variation in price from different sellers. Of course, there are numerous reasons for this. But wd some people really go to the trouble of making fake blades? Have any of you suspected you may have bought fakes? I,ve only ever bought them through ebay. Is there a safer online option? I'm in the uk, so over the counter has never been an option.
