I saw a couple of new items that will be coming out from Petzl next fall.
one is a new super light ice screw called the Laser Speed Light. it's a little more than 1/2 the weight of their previous screw. the shaft and hanger are aluminum and the teeth are steel. apparently they have come up with a new design for the teeth that really bite. it's impressive...
the other is an ice screw sharpener called the LIM'ICE. it has a handle that moves back and forth. there are 2 holes that you put the screw into and move it back and forth and it cuts the correct angles on the teeth. I want one of these NOW!!!
unfortunately both of these won't be available until next season [SIGH] but you can check them out here:http://www.petzl.com/us/outdoor/new-2013-lighting-iceclimbing-0
