Actually I suppose, the keris in Blu Erf's post (#8) is not correctly depicted, if I take a look on it's shadow. It could be longer then it seems. A pity we don't have more and proper pics of it. 
 
As David stated, we see three absolutely different style keris in post #1, and material of them is of very different quality. 
 
Here is one similar to post #19 with talismanic inscriptions.
