Hello Alam,
yes, the blade looks a little bit crude. But I have the hope that it is better in real, like yours or nine from this thread:

Interesting in my opinion is the handle. Not only at Jensens Kris disc I have seen a keris from Sumatra with this form of handle also somewhere else but can't remember excatly where. Some other examples from members with this handle form?
Regards,
sajen
