My favorite screws!

By Matthew Agarwala Ranked #66 - Ice Climbing May 6, 2010

These are by far my favorite screws and they make up the bulk of my ice rack.
Pros:
1. rack easily using the petzl caritool, but not so well with the BD ice clipper. 2. tips come sharp and stay that way, i've never had an issue with dulling the screw.
3. Fast, efficient, effortless placements every time.
4. rotating, swivel handle lets you get the screw in tight spaces without having to excavate away all your ice.
5. easy for the second to clean

Grivel screws have cone shaped threads instead of triangular ones. The idea behind this is that each thread has more surface area in contact with the ice, thus creating a stronger placement.

I recommend these to all my ice climbing friends. The only other screw that I use is the petzl laser sonic
