How does Jim's pride disarm him twice?

Finally, when the tide is out, and Hands tutoring Jim, the boy manages to bring the ship to the shore, a difficult feat of navigation. Completely enthralled by the landing (pride), Jim forgets that Hands is armed and dangerous and he is nearly stabbed but jumps and turns out of the way just in time to avoid the approaching Hands. That's the only one I can think of in this chapter.
