well 3 section staff s roughly bout 7 ft to 9 ft long, depends on how tall you are, i heard this b4 but i dnuo wether its true or not, each section should be da length of your arms n da 3 diameters of da 3 section put together, u should b able 2 hold it.
it was made n 960AD by this dude called chao hong-yin. he had a staff and got attack by this chavs and his staff broke into 2 pieces, he ran 2 this blacksmith n he used 2 rings n joined his staff back into 2 (one big one small), he try his revenge but da long section out of the two was weaken and broken into twain. so dats how da 3 section staff was created
its a long n short range weapon, u can extend it and use it as a powerful whip, or hold the both ends and use it as a trapping weapons (good at close combat)
advantage- powerful, long and short range weapon, easy to carry (ish, well cost cheaper for pnp on ebay then a normal staf so...), can attack and defend in the same time, hard to defend
disadvantage- hard to uses, could lose momentent in a fight,
