What kind of collapsible walking sticks would fit in a Rick Steve’s’ carryon

Im using LEK foldable walking/hiking poles from REI in my Rick Steves carry on bag. The collapsibe poles come in their own carry bag. any foldable/collapsible hiking pole should fit just fine.

Just be aware that not all walking sticks are allowed in carry on luggage.

This from the TSA:

Blunt-tipped walking sticks are allowed in carry-on or checked bags and must be screened like other property. Sharp-tipped walking sticks are not allowed carry-on items. Please note that even if an item is generally allowed, our officers make the final decision on whether an item is allowed through the checkpoint.

Check with your airline to see if they allow walking sticks as carry-on items.
