Ok maybe the difference here is like Alex said "who is doing what",,,

I am not so sure that end users should be popping apart razors.. JMHO

As to taking razors apart with peened pins, I do that almost every single day... Ahhhh and that could be the rub, I do it almost every single day and I have the tools and talent to do it right....

I also have had to clean up a pivot hole very, very, rarely, I do sleeve the over size ones though..

We have gone way beyond what Chris asked in the first place though, which was how do you keep adjustables tight????

I leave that actual answer to those of you that use them, because my answer to that question, from my experience with them is a "Wrench" ....often...
