I've taken a 173gram Valkyrie to the collar bone. It wasn't that bad...didn't even take me off my feet. Plus i've seen a bunch of buddies of mine take some sick shots to the head or caught a mean ricochet from a tree 10 ft off the tee pad. But I can see that if a disc were to hit some place vital it could quite possibly cause significant damage...
To some cultures, if it can be thrown, it can be a weapon. The word disc undoubtedly comes from the Latin word discus...which we relate to the Olympic sport..an event since the very beginning of the Olympiad and as far back as ancient Greece...some several hundred years before Christ.
If they were throwing it in ancient times, it was a weapon of some sort. I'm sure there were many variations of a thrown weapon like a disc throughout the centuries.
In Hindu text or scripture, which has it roots in the east...it was known as a Chakra.... a most deadly weapon. It was serrated and bad ass.
Thanks for the link, but, 160 is too heavy. The limit is 159.9, and trust me, when tournament time rolls around, that .1 makes a difference. And 159.9, Open Class, is only for certain tournys. Half the scheduelle is 152.0 max. I've had discs that I bought Stateside that were a point off and got rejected. All discs bought outside of Japan must be weighed and stamped prior to tee-off. At the Tokyo Open last year, I lost my three main drivers and main putter prior to first day Tee-off for a .1-.2 gram infraction.
