i use plastic washers between the head and handle of my razors, they usually just fall off when holding the head after removing from the handle, the razor and head came with a little rubber washer attached, and i decided to just leave the rubber washer on, after first use the rubber washer was stuck on kind of like a suction, i had to fiddle to remove it, hence why i sliced my finger, i binned the rubber washer and replaced by one of my plastic ones, just be careful if yours has the rubber washerFirst post
I have one of these on the way and a good stock of Astra's, so it'll be interesting to see if my experience agrees with yours.... Fingers crossed mine doesn't stick together like yours has, I've still got the scars from a similar experience with an R41 9 years ago!!
What I can say, for any interest it may provide, is that in my Mamba .70 (that this is supposed to be a copy of), the Astra is nice but the real golden blade is a Treet Carbon - only for two shaves, but two incredible shaves... An odd blade though, excels in some razors and nothing special at all in others - a true YMMV blade, especially if your razor varies.
