Make a set of ice rescue claws
Instructions for Making Ice Claws
1. Get two 4" pieces of wooden doweling the size of a broom handle or a little larger. Whatever material you select, it should float in case you drop the claws while struggling.
2. Drive a stout nail into one end of each dowel. This should be a hardened 16 penny or larger concrete nail.
3. Use a file to sharpen the nail heads to a point.
4. Drill a hole into the dowels (in the end opposite the nail) and tie a length of strong cord through the hole so a pick is on each end "jump-rope" fashion. You may also drill a hole in the ends alongside the nails so the nail on the other pick can nest in the hole, keeping both points covered. Keep the picks in your pocket for quick emergency access if you or a companion do break through.
