In reply to Jamie lewis walker:
> I don't know what you would have to do to put a hairline fracture in a crab but I'm pretty sure its a lot more than someone taking a fall on it, if it does get damaged in that way from a fall then i would say the product would not have passed safety regulations in the first place.
Have you seen the demonstrations at the ( DMM ?) factory?
Everybody hammers the f*** out of a krab and then it gets tested in a pull machine, always still well strong.
For years it was taboo to use a dropped krab until it was proved to be bunkum.
I will probably get corrected but the main problems with karabiners are corrosion on sea cliffs and rope damaging scores from weighting bolt hangers, and the odd worn out gate spring.
