From the manufacturer

The Black Diamond Expedition Carbon Pro ski poles are designed for daily touring missions. 

Featuring carbon construction, our FlickLock Pro connector makes the length easy to fine-tune, and a PH3 screwdriver bit and 1.5mm hex bit are hidden in the lower shaft for field repairs in a pinch. Extended EVA foam grips, a straight-edge grip-top for scraping ice and snow off skis, and a tactile rubber “beak” for quick binding adjustments on the skin track all contribute to the simple yet useful feature set of the newly redesigned Expedition grips. Girth-hitched straps are easy to remove if you choose.
