Does anyone have a good method or technique to re-blacken a set of fuchi kashira that have essentially been rubbed clean over the years?
Specifically I have a few old Hanwei blades where the alloy fittings could use some attention, so adding a new durable finish would be something I wouldn't mind trying.

I've found powder coating to give decent results. How it was ![410542347_1521186258735005_5070588282121572....jpg](//storage.forums.net/1694914/thumbnailer/GgdxFecdGzcsqIsulRpy.png) After coating ![434182456_428362129746811_32035212048826290....jpg](//storage.forums.net/1694914/thumbnailer/bCIFZMzBoKmNuDkEUvsW.png) After sanding ![428310737_396382559637504_74352558774258458....jpg](//storage.forums.net/1694914/thumbnailer/PptDxoNmFEKqJlJlMYtQ.png)

The powder coating doesn't look bad. If they're brass I'd use the Japanese iron patina to darken them, or maybe liver of sulfur. It will give a more durable patina than a paint type treatment, and they can further patina with use. That being said, if they're the Chinese mystery metal mix, pretty much the only option you have is some kind of paint type mix. You can try to patina them, but they're probably going to end up looking like something from a sci fi movie. If you know the alloy composition better, there may be other techniques to try.

the Hanwei fittings are usually a stainless steel alloy and they don't take traditional or chemical patina too well. I'd go with a durable paint or cerekote/powder coat instead.

Yeah, stainless is also quite hard to patina nicely, you've got some good suggestions there.

Cerakote would work, and can be weathered if you would like, but as a former applicator I would highly recommend you properly prep the surface with either an aluminum oxide blast or garnet sand. It’s essential for the cerakote to bond properly with the substrate. If done right, the finish should last quite some time as finger oils won’t wear it.
