keris and spirit

[Pusaka]

Let’s say it is possible to imbue a blade with an energy field, call it spirit if you like but what type of material would best suit this purpose?

As an analogy I would like to consider the basic bar magnet. There are many types of magnets, natural loadstone, common steel magnetized (the first manufactured magnets), nickel steel and super strong rare earth magnets. The nature of the magnetic field in all of these substances is the same however some materials when energized (magnetized) will retain that magnetism for a longer period of time.
We conclude that it is possible to magnetize several materials but some make better magnets then others.

In terms of magnets what type of material makes the strongest magnet?
As stated previously rare earth magnets are the strongest type of magnets available. One variety of magnet which is extremely strong contains three main ingredients, nickel, ferrite and a rare earth element. The smallest quantity of rare earth element when added to a nickel iron compound will boost its magnetic properties.

Meteorites often contain iron, nickel and rare earth elements. A kris forged from meteorite should be more magnetic then a steel blade.
I was once told that a keris made from meteorite was better able to hold a spirit, I read earlier in this thread that a keris made from meteorite was able to hold a spirit because it is yin.
I will however say that a keris made from meteorite is better because it contains rare earth elements which makes it a suitable object to be energized and retain that original energy for a longer period of time.

All magnets become weak over time if they are not remagnetized, all keris will likewise become weak if their energy if not maintained in a correct manner.

It is not mystical, its Scientific
