Just one quick thing before you go tearing the razor apart,

Hold the razor up in front of your face, closed with the tail pointing straight at yer nose, look at the pivot end and see if the scales are straight....

If one side is higher than the other, that's the problem.....
Sometimes you can spot other problems here also, like a bent pin, badly drilled holes, an uneven tang... Oh yeah!!!! you didn't really think these were all ground perfectly straight did you????
