A close-up view of the trigger mechanism.
The vertical stick that holds up the deadfall is
pointed at the end. This aids in rapid triggering of the trap.
The surfaces of the bait stick have, in this case, been
leveled out. This provides a more stable surface for the vertical
stick to rest on.
To make this trigger more sensitive, the bait stick
could be left rounded, and one could select a more rounded rock.
