Ski stick

Without wielding a ski stick, skis are useless. You will fall every time you try to ski and hurt yourself a little. Contrary to popular belief, wielding two ski sticks does not boost your speed, and may even slow you down. While the description for Northern spears state that they can be used as a ski stick, they do not function this way. This is likely to be a bug.

To make ski stick you need an axe, a slender tree trunk and 1 lbs of leather.
