Managing bamboo which have thorns

I have a bamboo variety which is very common in Kerala and this has thorns on it. I got this saplings when I attended one session in Yuvakshethra college Mundur. I didn't realise the difficulty in managing this species when grown up. It would have been close 9 years since I planted and it grew to a big clump. Few years back, I sold it to a person who cut its small branches which will be used for making fence.

I like any biomass creating trees, but this was just difficult to cut with that thorns,cut few of the poles with chain saw, but were not able to pull out them so just left it as it is. Compared to this I like all the bamboo varieties which are thornless and easy to cut.
