Unusual color on Kris blade

Spunjer · 4th January 2009, 05:22 PM

has anyone seen this color on a moro kris blade? at first i thought it was dried up cosmoline, but the coloration is uniform throughout, save the edge part where it's been sharpened. the edge has a regular steel color. as far as the color itself, it's a light olive drab, kinda brassy. i'm really beginning to think the blade is indeed made out of some type of brass, but with hardened steel edge. the asang and ferrule are copper, btw.
when i first got it, i tried to use acetone, then water steam, but non of it made any difference, meaning i can't remove whatever it is. i think the blade was deliberately done this way. any comment on this???

btw, the grip on the handle is unusual as well; it's covered with a leather like material:

I have seen this color in steel before. I don't' think it is brass because the heat differential between brass and steel is too great. Interesting back part near the hilt.

Sometimes when trying to stain a blade, I used tap water mixed with FeCl and got a color like that. Now use distilled water.

Atlanta water is so bad and atheist could walk on it!

If it is a stain, chemical removers won't help. Might try some 900-1000 grit sandpaper with water or WD40. Bet that will clean it off.

Hi Spunjer,
The only thing that I have ever seen like this before was a dagger. It had a steel core that included the tang with a nickel bronze, not brass overlay. Is there any place one the blade where you could test it to see if it is bronze without doing any damage? Maybe you could remove the grip and if the blade has a separate gangya you could test it in between where it wouldn't show. What ever it turns out to be it is a very interesting piece.

Hullo everybody,

I don't know whether it's the same thing, but here it is:

I have a moro kris which had a similar colour to yours and felt like some kind of plastic film. I wasn't too concerned at the time, as I was more concerned with getting rid of some rust spots on it. I brushed the blade with citric acid. After a while, not only did the rust spots clear,but so did the green /olive film/coating. It's not 100% clear at the moment but it probably will be the next time I wash it.

Best,

thanks all, for the comments! my concern regarding this blade is whether it was done deliberately to look like this, or was it applied artificially, accidental or otherwise.
i took some closeups using natural lighting. i did notice that there was a couple spots in the katik where it was coming off. at the moment, i'm kinda partial into being done deliberately. it's too uniform throughout the blade. even on the smallest parts, such as the elephant's trunk, is covered with whatever it is. also the edges appeared to have been sharpened after it was applied. robert, the overlay sounds interesting. kinda like plating perhaps?

it started to drizzle...

Spunjer,
Yes, like electra-plate. Very smooth as if it was polished after being applied but with the same aged look as the blade you have posted.
