If you geek-out hard about alpine climbing gear, you will have noted that many manufacturers have begun to develop handy, moveable, pinky or trigger rests for Mountaineering axes. Some of the more popular axes with this feature are the Grivel air tech evo (equipped with the “slider”) and the Petzl Aztarex.

Grivel Slider

The consensus has been that the Grivel slider (available as an accessory) is nice but requires some trickery to adapt to a non-Grivel tool.

And the stowable pinky rest on the aztarex, while slick, is a major pain to stow/deploy.

With all these issues with the oh-so important modular pinky rest… What is one to do? Enter the new Petzl Trigrest as featured on the new Sum’Tec…

The Trigrest is an interesting modular pinky rest. Although this gadget is most prominently featured on the new Petzl Sum’Tec (which was introduced to North America at the summer 08 Outdoor Retailer show), it is also available for purchase as an accessory. Best of all, it fits on my many popular tools. The orange tab acts as a sort of friction lock (I guess a bit like a quick release skewer on a bike? if you will)

Undoubtedly, Petzl did not have this application in mind when offering the Trigrest as a seperate piece. In fact, they explicitly state that it is made for the Quark and Aztar axes exclusively, it seems to work quite nicely on this and I assume any other similar sized axe. I prefer this to any other mod out there that I have seen, becuase it does not require drilling and is comparatively inexpensive.

I’ll keep you updated on how it all works out in the mountains…

As is noted in several comments, this Trigrest has it’s shortcomings. The Orange lever is certainly in the way when utilizing the pinky rest. Not only that but it just does not have the holding power to eliminate the need for stopping screws. A really great product, but best suited for the axes that it is recommended for.
