Welcome the new Game Of Thrones season wearing Jon Snow's sword.
Longclaw is a bastard sword or hand and a half sword, which means it is a good half a foot longer than a standard long sword, tapered to thrust as well as slash. With three fullers incised into the blade to reduce weight. There are ripples in the dark steel indicating it is of Valyrian steel. It has a bear's head for the pommel.
