Tim Tebow honored his favorite carpenter this weekend ... by chopping some wood.
Tebow's friend Jase Robertson -- one of the stars of "Duck Dynasty" -- posted a photo with the unemployed NFL star on Sunday ... showing Tim gettin' his Paul Bunyan on with a trusty ax in hand.
Jase added the caption, "Working out with @TimTebow. #OperationBiceps."
Turns out Jase and Tebow are pretty tight -- in fact, they're both speaking at the 2014 Wildfire "Men's Impact Weekend" religious conference at the University of South Florida in June.
