I was curious about ice claws and found this informative: http://lakeice.squarespace.com/ice-claws/
Edit: and if I'd read a few comments down I'd have found this without Google.
If you have been swimming in ice-water, you already know that you survive several minutes without a problem. Ice claws hanging from a neck strap make it easy to crawl into safety. You have dry clothes in watertight container in you backpack if you are far away from warmth, of course.
