I'm trying another approach with better results at least with this one I'm getting close to metal "slightly Look"

Blank canvas with a monochrome linear gradient, search for the best angle
From the photoshop filters menu, choose Filter -> Noise -> Add Noise
Apply the "noise" to taste
Filters -> Blur -> Motion Blur, applying blur to the pixels horizontally. play with how much the pixels are blurred
Also try different opacity and scale percentages with the monochrome linear gradient
This is very very basic, now the gigantic step will be apply this to the Sabre, some thinking will be needed

Comments are very very welcome
