I really like
Coghlans folding scissors. I've never tried taking them through airport security, but they're part of my EDC and at $3.75 if TSA takes them you won't be out too much. Put a second set in your checked bag. Scissors are so non-threatening
TSA WEbsite :Scissors - metal with pointed tips and blades shorter than 4 inches are allowed, but blades longer than 4 inches are prohibited.

Obviates the need for tp, eliminates laundry expense, serves as dandy field-expedient wound dressing, reduces in-flight cabin movement, and the soft rustling sound that accompany ambulation acts as a bear bell to prevent unwanted confrontations.
