Thanx Robert . Yep oxalic acid dip. I would have done the scale's logo if it was deep enough to hold the paint but I think its too worn.

Thanx Stu, unfortunately like a few of us here, I often suffer from "before pics dementia"



Thanx Grant. Dunno if it's technically bluing or patina but I used an oxalic acid dip like on this...

Not quite restored to original but close :)
Complete strip down & clean up & tang was re blackened. Blade was not too bad & responded well to 180 - 600 grit SiC coated buffs followed by compounds...
