A tool is evaluated in response to a member of the tool being moved from a first
position to a second position. In this evaluation, a first force is applied to
the member. The first force is operable to move the member from the first position
to the second position. In addition, a second force is sensed. This second force
results from a resistance of the tool to the first force. Furthermore, it is determined
whether the second force exceeds a predetermined value.
