Yep, I'll stick with the science and engineering of metals, you can stick with your anedotes.

I will add an apology / correction. I shouldn't have used the word "internal" and instead using the words "which are not obviously visible", so that sentence should read

>>”If the binas at any stage of their lives have been dropped onto a hard surface from up a few metres, I'd be worried about which are not obviously visible cracks.”

While internal cracks do occur with metals, there is a much higher chance that it will be a surface crack. However, not all cracks are visible to the naked eye and may not be detectable even with the aid of NDT crack detecting techniques, and it’s these cracks that you need to be very careful of, with carabiners which have been dropped. I still stand by my comment that internal cracks are possible from a metallurgical view point.
