Little keris for comment and a few question

[A. G. Maisey]

How long is the blade, how long overall?

Looking at the two keris, side by side, I'd probably call this a patrem, provided the other keris is normal.

If requested a m'ranggi will use whatever means & joints work best to make something functional.

Have I ever seen precisely the same joint as this?

I don't know, I've seen very many & I do not remember them all, but if the m'ranggi decided that joint would work best, that's what he would use.
