an old keris tok chu..but is it from the master?

Hello gentlemen,

While I didn't do any study on the magnetic properties of the keris, I want to highlight that ANY ferous object has some degree of magnetism as it is directly generated by Earth's own magnetic field. You can test this by aproaching steel spoons, scisors, knives, watches, etc. to a compass.

Moreover, most mechanical processing mechanisms, whether through plastic deformation or throgh chip removing, produce additional magnetization of the ferrous materials.

Last, but not least, the magnetic properties of a metal are greatly influenced by its composition and crystalline structure.

So I do not believe that magnetic properties of a keris can be considered as an indicator of age or quality, unless they are scientifically assesed.
