This is a custom 2nd grip for the Grivel X-Monster Ice axe. If you own one, you know that matching grip on it is very difficult/painful.
This is a very lightweight addition (to an already heavy axe) that really adds a lot of comfort and function.

I've tested mine with many figure 4's on overhanging rock and its held just fine. However I ASSUME NO RESPONSIBILITY for what you do with this piece. :)
