Shiny pencil with Inkscape
Here is another nice screencast from Heathenx. I think it gives a very realistic effect. I was particularly with the technique for copying metal shine into a multi stop gradient. Instead of using the photoshop image like Heathenx I got a photo of a real steel cylinder from Google. Very handy technique going forward. Here is my effort: Not quite as elegant as the tutor, but not a bad first effort I don't reckon.
