A pictoral representation of the UIAA-153 and EN-893 standards for crampons.
We made the NEW LIMITED EDITION Lightwieght series of bolt-on-crampons for fruitboots "Vacuum". They got this name, because - apart from the small weight - several vacuum technological processes were used for their production. Firstly, we used vacuum-arc remelted steel. Secondly, the front of the blank undergoes vacuum annealing, then it is hardened in vacuum. Thirdly, for the frontpoints' coating we used a vacuum deposition of silicon oxide technology.

The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.
To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.
This video shows how to sharpen your crampon correctly.
I’ve been using the Vergo for several months now, and one of the reasons Trango sent me one early was because they knew I’m a huge GriGri fan and very skeptical of competitors. Before the Vergo I would have said there were some OK alternatives, but nothing I had tried would ever replace the GriGri for me. That has changed with the Vergo, as much as it pains me to say anything negative about my beloved GriGri, and there are plenty of days when it’s the only device I take with me to the crag.
