Weapons grade Javanese kerises

No, the full length of a blade is never heat treated. In a Javanese keris the length of blade subjected to heat treatment varies from only the first couple of inches through to a point just below the poyuhan --- or where the poyuhan would be if a keris does not have a sogokan.

Hi Alan,

Ignorant question, but wouldn't heat treating a keris potentially induce fractures, because the different metals in the pamor expand at different rates?

Best,

If the welds are good there is no problem. I've heat treated a lot of mechanical damascus blades using various ferric materials, as well as ferric material + nickel. I've heat treated keris blades using the same types of materials, I've heat treated one keris blade and a number of knife blades that used meteoritic material, and the only failures in weld joints I've ever had were two or three very early blades I made when I was still learning.

If the weld is good there is no problem with a heat treat.
