Very wise words Kai Wee.
Sakhti, i am curious about how you manage to read chi from an internet photo. You must be powerful indeed. I have been doing energy work for years, but i always feel more comfortable actual holding a piece before proclaiming it's level of energy.
Sepang, you have shown us some interesting examples. The first one, which Sang Keris calls "green iron" is very interesting, but i wonder about it's condition. It certainly appears old. I have keris in my collection that are nearly 500 yrs. old that don't look like this. This one appears to have been excavated from the ground. I wonder why a keris of this powerful mystical type would have fallen into such bad care or been buried under ground. Do you know the history of where it was found.
You "baby tree" example appears to me to be an older blade that was altered with these carvings at a later date, but the examples you show in the middle may well be authentic. I am afraid i lack Sakhti's skills to be able to determine this from your photos.
