You never know when you need to fix something. That's why I carry a Knipex Mini Cobra prier & Mini Pliers Wrench with me everywhere I go. I take them in my carry on bag when flying and I've never had a single issue in the last 4 years of flying. My bag almost always gets pulled for deep search due to my camera gear and other 'odd' things I carry. Never an issue if I'm kind and explain what things are. @knipex_northamerica @knipex_official | TOOLS by Design
