The competitor makes one cut through 19 inches of white pine using a single man cross-cut saw. The competitor may have a helper wedge his cut into the log to prevent the saw teeth from sticking.
Time ends when the block is clearly severed. The primary challenges of this event are technique, brute strength and stamina. The single buck is referred to as the "misery whip" because of the physical toll a body endures while using it.
A key strategy is to keep the saw as level as possible so that it creates an even cut and the teeth don't catch in the wood. New Zealander and 2009 STIHL® TIMBERSPORTS® Series champion Jason Wynyard set the world record for the single buck at 9.39 seconds in 2007.
