Hello David, I know I am a bit of a wonderer but I do like to visit occasionally
Kiai,
I need to explain myself clearer because I think my analogy has confused everyone

The energy that flows through a keris blade is not common magnetism and neither is it produced by magnets in any way. I don’t agree with Mr. Sanders if he says it is, actually I don’t agree much with anything Mr. Sanders says but that’s just me. I used the analogy of a bar magnet simply to say that the material a keris is made from can affect its ability to carry a current/energy just in the same manner the material from which a bar magnet is composed of can produce a strong magnet or a weak magnet. A keris blade is not made with magnets and neither are they traditionally used to energies the keris. I have noticed however that some keris are slightly magnetic, put the blade near a magnetic compass. Today when we use the term magnetism it means one thing however in the passed the Victorians acknowledged different types of magnetism for example animal magnetism (a concept similar to the Indian concept of Prana and the Chineese concept of Qi/Chi.
