The more I think about it, the more I think it may well be a mechanical/alignment problem like my broken Parat. The handle is aluminum and so where it’s pressed into the head it would be very weak. A design flaw I guess. Pretty much what romsitsa said above. That joint maybe should have been reinforced. It also makes sense to me that these broken, or partly broken razors make it into the antique stores and onto ebay. I can't recall exactly the gymnastics I have to go through to get the Parat open and set up properly so that it works. Pointless in my case because the handle separates from the head and there isn't enough metal to fix the press-fit.
