Naginata. It's a Japanese glaive. I got it from Bugei trading (www.bugei.com) back when I had a bunch of cash lying around. They may still sell them. It was not ultra expensive (but it wasn't cheap, either)
I studied kendo and iaido for 4 years when I was just out of college. I had to quit when I moved out of the area where I had found a dojo to a place where there was none, so I took up epee fencing instead for 5 years. I never settled down to any martial art; I was always trying them on for size then moving on.
I love the look she gives, every time I see this picture it's like 'oooh crap sheee's pissed...' then your mind wanders off to think about the setting. All I can say is that it wouldn't be pleasent to see her get out x9
