I've tried searching the vast amount of topics but not surprisingly there's so many on this forum about razors and blades that I couldn't find an answer to my question. If it's out there, sorry for adding unnecessary spam! I travel nearly every day for work which means I take the blade out of my razor every day, blow it dry and put it back in its packaging. Furthermore I keep track of how many uses I get out of my blades and tend to load them the other way around/upside down on subsequent shaves. Never really thought about this routine until now that I'm on holiday and CAN keep my blade in my razor. Does this affect performance? Do you guys turn blades around, maybe for 'even' wear of the edge? This question popped up because I've used a Derby Extra blade for the first time this week in my 37c slant, without taking it out. This resulted in two brilliant smooth three pass shaves , third needed four passes to get decent and found I had four weepers afterwards, first I've had in weeks even after trying out my Futur.
