Thanks Dave455, my question seems to have fallen into a pocket of ignorance here. I had a metal working shop for 15 years and have slung more steel than you'd believe. I do not trust chrome. Stress it and it pops up to cut you. I use my tools for work not as jewelry. The only good reason I've heard for using chrome sockets for automotive is they are easier to find when you drop them. I am restoring also, black oxide gives you options. Re-chroming is a pain, very expensive, and hard to find anybody. I've got Chrome and oxide wrenches. Believe it or not there's a difference in the sound they make. Nothing worse than full polish wrenches all scratched up. Always hated making a beautiful piece of steel and then having to paint it. Black oxide is as close to bare steel as you can get.
I think I'm pretty much with you!
I love my chrome tools, but if I was using them hard, really hard, I think black oxide or unfinished would be a better bet.
Corrosion isn't really an issue with tools that are being used daily, and as I said, steel quality is more important anyway. I have 'blacked' Britool wrenches from the 50's, (more grey now) made of superb steel, that havn't worn much and don't pick up rust. I've also seen chrome tools made from crappy steel that have rusted under the chrome - and when it peels it's sharp!
I'm sorry to hear that re chroming is a problem where you are. I have 4 really good chromers within about a 40 minute drive. Most of 'em charge by weight, can handle all the prep (including stripping old chrome or de rusting) and do a superb job! I just had the handles chromed on a drill I was restoring and there was change from £10 ($15).
I know that in some industries (I think petrochemical tends to be one) black oxide tools are the norm. I know a guy who worked in that field a lot. Semi retired now, but an awesome wrench collection, some obviously very old, and hardly any chrome to be seen!
Also, in the general engineering world, the majority of the tools tend to be unchromed. Chrome pin wrenches are rare, for example, and I don't think I've ever seen a chrome C wrench!
Food for thought!
