The real Shaolin staffs from the Ming period, when they were actually used for fighting against bandits and occasionaly in battle against Wako pirates. Were made of either wood or iron, were 8-9 feet long for wooden staffs and just shy of 8 foot for metal staffs. Wooden staffs weighed 3-4lbs and metal ones 19-21lbs.
They just had simple straight staffs with no connected sections etc...
Cheng Zongyou's ‘Shaolin gunfa chan zong’ (Exposition of the Original Shaolin Staff Method) published 1610 as quoted in Shahar, M, ‘Ming-Period Evidence of Shaolin Martial Practice’, Harvard Journal of Asiatic Studies, 61, (2001), pp. 368-369.
It should also be noted that even in the later 16th and early 17th centuries there were many schools claiming to teach Shaolin staff fighting that bore no resemblance to the Shaolin method and lacked any lineage to the monastery. Also that some contemporary staff fighting experts even considered the Shaolin methods to be substandard and went to the Shaolin monastery and on seeing what was being taught stepped in to teach them 'teh real staff fighting'.
