Toko has updated their Nordic Tech Manual after two-year without an update. Says Toko, "The Toko Tech Manual is written in a clear manner and includes what waxes and techniques to use, why, and when. It also gives a great overview of principles of ski preparation."
Recommended reading even for people who do not use Toko Waxes.
