There are too many carabiners for me to assemble a comprehensive collection, so I don't try. The only carabiner type that I actively collect are the specialty carabiners. If you would like to see a proper carabiner website, I recommend Sam Johnson's site:
I have accumulated a few "normal" carabiners over the years, including some interesting designs. I have not had and do not have time to research these. Aside from some thoughts on locking carabiners, I am providing only an image gallery here at this time.
