New kris/preservation advice?
 

Just acquired my first legitimate older kris. It looks to be intact (except for the scabbard) but in poor shape. I would like to clean the blade and try to preserve the handle. As you can see the cord wrapping around the this totally shredded. I do believe the pommel is banati wood.

Would appreciate any thoughts on the kris and how I should go about preserving it or even restoring the hilt?
