Curling is an Olympic sport with four players on each team where players slide heavy granite stones. The term throwing your hammer in curling means having the last shot at the end.
The word hammer comes from the Old English word hamor which in Germanic means "stone"

The last rock thrown in each end is called the "hammer." Having the hammer is an obvious advantage, since you have the "last say," so to speak, in that end. Whichever team does NOT score in an end inherits the hammer for the next end. At the beginning of a game, a coin flip determines what team gets the hammer for the first end.

A tendril is the term given to the thin curling part of a climbing plant.
This is called "blanking the end." In curling, whichever team scores gives the "hammer" (the advantage of having the last shot) to the other team for the next end. If no one scores ("blank end"), the team that has the hammer keeps it for the next end. If the team with the hammer has a choice of whether to score 1 point and give up the hammer, or blank the end and keep the hammer, they will usually purposely blank the end, carry the hammer to the next end, and to try to score more than one point in the next end.
