Position your hand in front of
the iron, so as to prevent it from
falling out during removal or
adjustment.

(Be Careful not to injure yourself)

Tapping the end of the iron tang
with a mallet should loosen the
iron and wedge for removal.

This is possible because they are
both opposing wedges. I always
totally loosen these parts every
time I adjust the iron in an
upward direction.
It really isnt a hassle as it would
appear.
