I always INTEND that my poles stay with me. But, one does have "senior moments" each day. Also, I distract easily...
So, putting contact information on these costly items is a good idea....IMHO.
Also, I use 3M reflective tape, cut to 1/2 inch wide x 2" wide strips around every segment of my hiking poles. This creates a four-band reflective strip on each hiking pole. It also marks my poles distinctively, differentiating them from other pilgrim's poles.
Marking my poles, both with the contact label and the reflective stripes, is something I do as soon as they are delivered to my home.
FWIW, when walking facing traffic, and if the oncoming vehicles have headlights on, I flick the right pole, from my wrist, in an arc. To the oncoming driver, it looks like a spinning propellor with strips. It ALWAYS gets their attention. Have not been hit yet, and all the oncoming traffic sees me early enough to move over. I can see it.
I hope this helps.
