Since the story involves an axe, an axe will be your prize.
There is a story that on April 8, 1865, holding his arm straight out, Lincoln picked up an axe by the butt, with the handle parallel to the ground, and held the 7-pound tool motionless. His strength amazed everyone who was watching.
I believe the provenance is good, and this particular axe is now at the Abraham Lincoln Presidential Library and Museum.
Just give the museum a call, tell them you got this question right, and arrange a time to have the museum formally present you with the axe Lincoln once held.
