Help with finding finish for steel handle on guitar case

design | patina finish I am a UK based designer. I have developed a range of cases for guitars and laptops I am unhappy with the look of the steel and hope to find something with a more subtle character - possibly patinated/oxidised ? I know nothing about this area and so would be grateful for any suggestions. I do not have to use stainless steel - it could be mild steel - but whatever steel/finish I use must stand up to being exposed to weather over many years. You'll see that the steel strip is recessed to take a strip of leather. Also note the screw heads are visible - and I need to be able to match the screw heads to the finish of the steel strip. I make to order so need to find a process that is cost effective in small batches. I try to minimise my environmental impact so this would have a bearing on my decision. I hope you can help. Thanks Nick ![]() Thanks

Rich many thanks - I'm glad you like the cases. I'll give more thought to using a wheel as you suggest. Now I've thought about it more I think I want to get away from the silver colour of the steel - have a darker colour which blends in more with the leather rather than standing out. Maybe I use should use another metal - bronze perhaps? I've seen a photograph of a stainless steel ring which has been heavily oxidised this seemed to have a lovely dark textured look - do you know anything about this technique? Best regards ![]() Nick, Bronze would be good,

Nick, Bronze would be good, but would need to be sealed if you're in a marine environment or it will develop a verdigris patina that may rub off on clothing. Stainless steel can be heated to red hot, as for forging, and will oxidize to a dark matte gray color much like mild steel. It will still be mostly stainless, that is, it won't rust unless subjected to salt air. If you heated the stainless sheet to red hot, then textured the sheet with a small cross pein hammer, you could develop a really nice surface texture that could have the high areas lightly sanded to accentuate the contrast. That would be a nice counterpoint to the very smooth lines of the cases and leatherwork. Hope this helps, Rich |

Nice looking cases,
Nice looking cases, Nick!
You might try surfacing the stainless steel using a Scotchbrite wheel. They're available in a variety of grits and will leave a consistent scratch-brushed surface. Varying the angle at which you use them,you can achiece swirl effects, straight lines, curves, etc. The same material is available in round wheels for bench grinders, die grinders and in sheets and belts for hand use and use on belt sanders.
Stainless steel is the right metal to use for long-term durability and maintenance. Another possibility is titanium, but it is more expensive and somewhat more difficult to work with. Stainless can also be electro-polished.
As a metalsmith, my first inclination would be to forge a texture into the surface of the stainless, something complementary to the lines and finish of the case itself. Metal is inherently plastic in nature and open to manipulation by deformation to good advantage. Worth considering, I think.
Hope this helps,
Rich
