"Everyone," Amundsen wrote in his diary, "will have two pairs of ski. On the first pair, intended for daily use during the polar journey -- fixed bindings [in one piece] will be used -- the original Huitfeldt bindings. On the other -- to be taken as a spare pair -- Bjaaland is making binding ears in two parts, so that they can be mounted during the journey, if necessary. The point it, it will take too much space to have the bindings attached."
