Hello Jean,
The result even exceed my prediction
I don't know why this keris has top part like that.
But, when I examine the pamor from the top part. I have just realized that the pamor is not exceeding the edge of the wilah. Thats quite strange to me. From my opinion, it looks like the creator of top part has calculated so the pamor won't exceed it's edge.
Also, the two side also have different shape of top edge. Does the top part (pucuk wilah)of this keris slightly tilted? Could you provide the picture of the top part rotated 90 degree? (From it's thin side)
Thank you
Best regards,
Joe
