Teemu Selanne took his skate with the blade facing his right arm and repeatedly ran over it to the amazement of reporters surrounding his stall at Joe Louis Arena. A piece of fabric was the only thing sitting in between. But Selanne kept moving the skate back and forth without a pause. "I think every player should have this kind of sleeve. This doesn't cut," Selanne said of the sturdy but flexibile piece of fabric. "If you have that, there's nothing." Ducks players have seen the gruesome injury suffered by Ottawa's Norris Trophy-winning defenseman Erik Karlsson, whose Achilles tendon was severed by the blade of Pittsburgh's Matt Cooke on Wednesday night. Selanne used the opportunity to display socks and arm sleeves he wears that are made of Kevlar, a synthetic fiber that has numerous applications and uses. Body armor is one example of where the high-strength fabric is a component. Ducks captain Ryan Getzlaf said the majority of his teammates wear the Kevlar equipment, chiming in with "there's no real point in not wearing them." "Same thing with Jason Blake," Selanne continued. "If he would have had this, he would have never cut his wrist last year." Corey Perry swears by the socks. Perry missed the final 12 games of the 2007-08 regular season when his right quadriceps tendon was lacerated by a blade in Colorado. "I actually like them," Perry said. "I think they're better than what we used to wear. I don't mind. I don't notice it at all. You don't even feel them. They're just regular socks. You can wear these every day if you wanted to." Not every player is on board. Ducks forward Bobby Ryan tried them but has stayed with the regular cotton or synthetic knit socks as a matter of comfort. "Knock on wood, I've never had that injury and maybe it takes that injury to wear those," Ryan said. "But I don't like the feel of them. They're tighter and a little different up top. But I just really like thin socks. I don't even feel they're on my feet.
