What, fundamentally, is wrong with my metal texture? I've been working on a metal texture.  The key, it seems, it so mix the glossy type with the diffuse type; and of course there are various other things you can do (like bump-mapping.)  I was wondering if someone among you could be so kind as to tell me why my metal looks like shiny plastic, I just can't get it right. 

Eh, this was supposed to be some sort of light-saber variant. Here is a copy of my sheet:



What I'm really asking is what to look for.  I've tried about 100 variations on this and I still can't quite nail it down.  

The blend file is here.
My experience with metals has been that you need to include much less diffuse and much more glossy. I would try setting your factor value to something more around 0.05, or less.

In fact, if you're going for something more shiny I would try simply a glossy shader, with a roughness of about 0.05.

Hope this helped.
