Attempt Direct Claw Hammer Pull

What happens here

The person attempts to pull the newly driven nail using the claw end of a standard claw hammer. By applying direct upward force, the nail is only partially extracted, demonstrating that this method might lack sufficient leverage for a nail that is seated firmly or driven deep into the wood.

Goal: An initial attempt to pull the nail directly using only the claw of a hammer proves less effective for a deeply set nail.
