I think how they're breaking is when you slide it up and out, the natural tendency is to keep pushing it towards the side. Just push it slightly up so it's barely out, then grab it and pull it out. That way you're only exerting the sideways pressure on the thicker top part, and not on the spindly hollow silver barrel or where it connects to the top, which is probably the most common place the break occurs.
