I am thinking of getting some of the Costco carbon fiber poles next time they are available. But I was wondering how do you know if the poles get damaged? For carbon arrows, there is a flex test where you flex the arrow. if fibers are broken you will hear it and pitch the arrow. Releasing a bad arrow can arrow can explode and send carbon everywhere including into your hand.

Carbon bikes are also sensitive. if your bike falls over on to a hard edge it could ruin the bike. Much harder to know if it is damaged and if it is damaged you could have a catastrophic failure at 40 mph on a down hill with serious injury.

What a about trekking poles. With so much bang around on rocks, dropping them etc. Do they become damaged? Do they explode just when you need them? Or is it lest traumatic?
