So I noticed today while changing my Lord L6's blade, that the blade can slide a tiny bit in either direction before the razor is being tightened down completely. If I tap one side, the blade will be slightly slanted. This is because the two posts on the outside are a bit too small for the holes in the blade. I tried doing this with multiple blades and got the same result. Anyone else with a L6 or a 3 piece razor notice this?
Same thing with many of the razors I use. I just grab both ends of the head, try and make sure the blade is centered, then tighten down. Really, though, I find it isn't so much off center that it would ruin a shave.
