There's this town with two blacksmiths - one, a swordsmaker and the other, a shield maker. The swordsmaker's swords can slice through anything as a rule and the other guy's shields cannot be destroyed. Now they get cut up with each other for some reason and pit their wares against each other. What do you expect happens?
The outcome is either:
-The swordmaker wins, because he slices the other man's sheild in two--not destroying it, but rendering the sheildmaker helpless, OR
-The swordsmith kills the sheildsmith by stabbing around the sheild.
Either way, the swordmaker will win.
