Couldn't even get through the WTG pass with 1912 today before having to use the Slim. Hopefully these are just a few bad blades (although the first one was GREAT!). Will be popping in my last SE blade tomorrow and keeping my fingers crossed.
Which Gem blades? I have Blue Stars here that have been just fine so far, but one of them seems to be like the Energizer Bunny -- "Going and Going". All I do is let it dry, out of the razor(s) and it isn't rusting or showing any marks of any kind. It's got about five shaves on it so far, spread out over a couple of weeks or so (I only have a small collection of SEs, and I'm using them a lot, but not exclusively, for June).
