Saw to borrow please!

Hi everyone, I have a small metal pole that needs trimming. I bought this curtain rail (link below), not realising it wasn't wood, and just need to borrow a tool to trim it down please. Apparently I need a hacksaw? If anyone has any advice on what I can use to do this/better yet the tool to do it with I would be forever grateful. Won't need to borrow it for more than 5 minutes!

Am based near Tessa Jowell.
