Since we decided to rename our "polypropylene samurai sword" to the "indestructible plastic samurai sword", there has been a lot of controversy around the KarateMart.com office about whether this item is really indestructible. On the one hand, as our legal team explains it, "it's not technically indestructible, guys." On the other hand, the polypropylene material makes the sword tough and flexible so that it will weather all kinds of thrashing.
As we batted these swords around the office, it occurred to us that we didn't actually know the limit to the indestructibility of these plastic swords and that we should figure this out for you, our loyal readers. It also seemed a better use of our time than "accidentally" breaking the legal guys' coffee cups. So here are a few things that may or may not destroy your indestructible plastic samurai sword.
