I guess the point I was trying to make was that the super-strong umbrella in question (The Unbreakable Walking-Stick Umbrella) may be great for handling an army of watermelons, but what good is that if a 20mph wind inverts it and it is ruined? You're much more likely to encounter wind than enemies.
So the question remains. How strong is it in dealing with wind and rain?
