Tattoos

I don't have a single tattoo. I've thought about the tattoo I've drawn here (mad paint skills) about 5 years ago and I still like the idea of it. Offcourse it looks a lot better in my head but still. I'm still thinking about getting it on a black flag with flames behind it or just flames behind it. I still don't know just that part after 5 years. The spanners (is that the correct word?) will be in size 10 and 13.

(it's the idea, it should look angry)

What's the bit above the spanners?
