You are ALWAYS taking chances when you try to take hiking poles as carry-on an aircraft. In the US, TSA considers them a potential weapon, because of the hard carbide tips. They are correct, these ARE a possible stabbing weapon. You should presume that the Europeans think the same way too.
I suppose that, if you figured out how to remove the carbide tips, but retained the rubber tips for hiking, purposes, you MIGHT be able to show the security official and explain that these are "walking aids," (not different from a cane) and do not have the sharp tips. But, if you get some officious little twerp who looks on the list and sees hiking poles - NOT PERMITTED AS CARRY ON (without differentiating why) then you will lose your poles and you have NO RECOURSE...in any country.
Do not presume reasonableness...you are dealing with bureaucrats who do a important, but repetitive, and largely thankless job all day, every day. They are not known for being creative at interpreting the rules. it is easier for them to just say "no," as they have the written rules behind them. They will never get in trouble with their superiors for saying "no" to an item. But if something very bad happened on a flight because they said "yes"... that is why they tend to be overly cautious.
That is also why I ALWAYS check my rucksack. I attach the collapsed walking sticks together with rubber bands so they do not shift around. Then I fasten them securely in an outside side pocket of the rucksack using the available straps. Lastly, I place the entire rig in a brightly-colored, nylon laundry bag I obtained in my local DOLLAR STORE for ONE DOLLAR. There is usually room for other soft items as well.
I affix a luggage tag with my first night's destination lodging to the rucksack, and again to the outside of the laundry bag. I cinch the laundry bag closed and double-knot the poly cord. On arrival, the outer laundry bag becomes the rucksack liner, and doubles as a laundry bag (doh!) when not used as a pack liner.
DO NOT attach a home address tag, as they will likely send your bag to your point of origin. You usually only use your home address when you return home.
Think about it, if your bag is lost while you are on your way to start a Camino, you want the airline to deliver your bag to where you will be the night of arrival, NOT to your home. Conversely, when you are returning home, THAT is where you want the airline to send your bag if it is lost on the return leg.
FYI, I use my "auxiliary" 20-liter sil-nylon day pack I carry as a "possibles" and shopping bag as my carry-on for all my electronics, medications, documents, and stuff I must have on arrival.
I hope this helps.
