Perhaps the cheaper brands of poles don't use true carbide then, because like I said above, a pair I had, the "carbide" tips became nothing but bald little stubs after very little use with them. Once those tips became bald stubs, I didn't feel I could safely rely on them to grip any grooves in any kind of slickrock if I ever stumbled. That was a pair of poles by Wilderness Technology from Rec Outlet years ago. Hence why I questioned the effectiveness of the rubber tips like
these. I had recently purchased a pair of $30 carbon fiber poles from Costco earlier this last spring to give those a try and were enjoying them up until this week when I had mistakenly set them against the side of my car with the door open. Wind got a hold of the door and swung it shut, snapping one of the poles right in half.
Of course, all the local Costcos are already phasing out their summer gear and all their poles are now out of stock, so having already exhausted pretty much all of my gear budget for the year, I'm now onto another cheaper pair from Rec Outlet that I'll probably be using for the rest of the season until I can afford some higher end Black Diamonds I'd like to get.
By the way, I can be counted among those though used to look upon poles as something only "wimps" used until I learned of the reasonable benefits they offer as has already been discuss above (safety/stability, pacing, reduce weight on knees, multi-use as tent/tarp poles, etc). Now I only strap them up when I really want my hands free for scrambles and boulder hopping.
