Replying to Cutting Poles?

I bought the K2 PE ski poles towards the end of last season and I haven't used em'yet.
My problem is that I bought them at 50" and at 5'10" they're a bit to long for me. I remember reading on here back when I bought them that this is fine and they can simply be cut... I just don't really remember how.

How would I go about cutting them to better fit my height? Seem the handles are on their pretty tight are they glued on or meant to come off... or what?

Any help is greatly appreciated!

Thanks
