Petzl Laser Speed Light ice screw

One of the more interesting of Petzl's latest product announcements is the Petzl Laser Light Speed ice screw - a screw with an aluminium main body and a steel tip. It weighs 100g (for a 17cm screw) and has a folding handle. The older Laser Sonic weighs 185g for a 17cm screw, while a Black DIamond Express weighs 145g even with a slightly shorter length at 16cm. I would be interested to see exactly how they have made the connection between the two types of metal, because seamlessly joining steel and aluminium has in the past been a bit of an engineering challenge.
