Hi! I am flying from Paris Orly to EZE with Iberia via Madrid and for obvious reason I want to try to not check my backpack. I just can't afford to have my bag lost as I have another connecting flight in Argentina the next day to Patagonia. Plus, Iberia informed me I can bring 10kg on board which is plenty.

Question is what do I do with some trekking equipment which may be seen as 'dangerous': swiss army knife, hiking pole, tent poles & pegs...

Can I just stuff it in and hope it will pass? Worse come to worse can you give it to the airline crew to hold for me?

How strict is Iberia or Orly/Madrid airports?

Thanks!
