@ Lew - Nice keris!! Love how the batang sarung curves..
@ Willem - Very nice blade. It is hard to get a keris like this with 16 pamor layers (from what I can see) and still have good control between the layers. Most of keris like this that I had seen will only have 8 layers and even that the control is often not very good. Also, to me, the extra condong of the blade gives it an extra aggressive look.
I think the way some keris hilts are previously fixed (for lefty or right) probably can be seen at the bend of the tang. Some Malay keris will have a slight bend of the tang towards either side of the blade (if you see it from the front of the gandik). Probably to suit a lefty or a right handed person.
I noticed Javanese keris also have this feature. This is probably because that particular keris used to have a different style Javanese hilt (deity, demon etc) previously where the hilt is facing to one side as opposed to the standardised Javanese hilts where the hilt faces the gandik as we normally see. Of course not all keris with deity or demon hilts will have a bend tang. It is a matter of preference probably; the same goes for Malay keris.
The cool part about the standardised Javanese hilt is that it is ambidextrous. To me this is very convenient. Not that I had seen many keris, but I had never seen a Javanese keris with a tang bend for a lefty. (Probaby due to the ambidextrous hilt, preference and reasons that Mr Maisey had explained)
I had seen several Peninsula keris tang that are bend as if it is suited for a left handed person. Probably in the Peninsula, keris is still primarily regarded as a weapon and maybe to the Malays it does not matter which hand you use to give somebody a stab
