re: Pivot point - to oil or not
I hear what some of the folks are saying about the pivot point. My background just makes me want to respond - having fought corrosive environments for most of my first career.
A couple of things - oil gunk won't wear out a pivot point on a razor since it really doesn't have that much stress or frequency of motion on it. Indeed, if it gets gunky, then wash it out, blow it free of water, oil it. Gunky is always less desirable than clean but it is easy to fix it. Rusty is not as easy to fix.
Oiling a properly pinned razor won't make it floppy although it will certainly make it easier to pivot. If a pivot becomes remarkably easier after it is oiled, I would look for a corrosion problem. Of the razors I rebuild, all will remain at 45 degrees on their own - that doesn't make them stiff but they are lubricated and they aren't loose at all.
There are water displacement oils - if the oil 'sealing in the water' is a worry, then use one of them. However, I've never had that problem. If you do use a water displacement oil, use one of the ones developed for lubricating sporting guns. Which reminds me... the gun folks would never recommend that you DON'T oil a metal piece. They would say to oil it sparingly, though.
You should use an oil that doesn't dry to a varnish. The most obvious one that does that (and the bane of gun hobbyists) is WD-40.
Next time you go to a junk store and look at the razors or buy that eBay razor object that is well used, take a look at the pivot point. It will almost always be corroded. I've only found one or two that weren't. The way to prevent it is to keep it lubed and dry.
I recognize that there are multiple opinions on this so I guess it will be an individual thing. However, the next time you buy that new razor, read the directions. Of the new ones I've been lucky enough to snag, they mention that you should lube the pivot point.
Thanks for listening! I respect everyone's opinion on this so the above isn't meant to be a challenge or anything - just my observations and experience. I promise I will let go of the sock after this post. ;-}
