Replying to Cutting poles

Hello

I have just bought Line Dart poles, after a while I found out they were to long for my riding style. I just wondering if it`s possible to cut them down without making any damage on them. The Line Dart poles have an unusually grip, not like the one in the tech talk.

Anyway here are my poles and the tech talk:

Hoping to get an answer soon!
This is my first thread.
