A few weeks ago we put up a post on rope construction. Black Diamond has produced a little video entitled, "The Birth of a Carabiner." The video doesn't dwell on narration or anything else, it's just a quick peak inside a shop where carabiners are made.
Of course, once carabiners are made, a couple are tested from every batch. In other words, this is the death part of this blog.
The following video from Omega Pacific shows a force test on a carabiner. This is an awesome video. It's pretty intense to watch as the tester puts more and more and more pressure on it...
