Bugis keris for comment
 

Picked this up the other day the blade is in great shape so I fitted it with some spare parts I had let me know what you think. The blade is 13" long.



Lew

Nice blade Lew, with what appears to be a form of "standing" pamor pattern. :)
It's can be hard (for me at least :) ) to determine origin when all you are presented with is the blade, especially with the Bugis, who as we know, got around. But i think your choice of a Sulawesi hilt is as good a guess as any. It seems to suit this blade well.
Now...to find a sheath. :D

Nice old right blade with nice old right mendak with nice old right handle in nice bugis style!
Now the blade want to marry with a nice sarong!... and to meet warangan

Very nice blade, Lew. Just as a Bugis should be. No warangan for this guy. A Bugis blade is kept this way. Hey, I'm though and mean, I'm a warrior. (I quoted one of our members.)

One of those examples of good blade. Nice I must say. My preference, I like to have slightly etch with warangan to see slightly darkened, making it more fierce looking I thought.

Nice, very nice indeed. The hilt, hilt cup is a match for this piece.
The blade is a fine example of this form. Congrats! :)
I'm with Henk, no warangan for this piece, but a light fruit acids could perhaps darken the blade, a little.

I like, I like.....could the blade denote chieftain's piece?

Just like Alam Shah said and how it is done with bugis keris. Cleaning with fruit acid only.

in my opinion a little warangan could be nice to see pattern.

Here an example

True, but it looks more Javanese... don't you think. ;)
Anyway, it's owner's personal preference.

Btw, your's a nice example as well. Could we see the whole blade? :)

Marcokeris,

You have a very nice keris, but I go with Alam Shah. The condition of your blade is a bugis keris with his first etch.

The Prince of the Netherlands who passed away was given a Bugis keris, just an example like yours but probably with a more royal dress. A member of the staff of his late royal higness was instructed how to take care for the keris because the prince wished that his keris was looked after with the ceremonial rules, just because of respect. The staff member cleaned every period the blade with lime juice. And as we know the lime juice fade away the black arsenic corosion of the iron. So the blade of the keris of his late royal highness must have been looked like the blade of Lew, maybe a bit darker because of the etching with lime juice and the residu of the still present arsenic on the blade.

Very sweet waves, and beautifully executed greneng. Southern coastal Sumatran, I reckon. You may want to consider a sheath like this:

PS: keris is not mine. Was on ebay a while back. Sorry to the new owner, but just for reference please.
