Most useful items I tend to have are a folded up coat hanger
Thanks for reminding me to pack one into my Creek pack!
Not sure if anyone mentioned, but I also always carry a super minimalistic First Aid kit - a maxi pad (to stop bleeding), 2 things of Vicodin, few low-dose aspirins (I switched from Ibuprofen in case of heart attacks and clots) and Benadryl. Awesome tip on cayenne pepper, Dominion Rognstad!
