Black Diamond Express ice screw

Finally the screw itself is lighter, presumably from the reduced hanger weight. A 16cm weighs in at 5.2oz compared to the old model at 5.5oz. Not too significant: 17 of the old screws weigh as much as 18 of the new ones, to put it in perspective. BD's web site also notes that "all sizes of screws are now CE-certified," although their own comparison table still lists the shorty 10cm without the CE logo.
