Dear experts
for those of us with less knowledge it would help greatly when you introduce a less common keris term if you can identify on a picture that element or at least give a brief description. For example in this discussion ri pandan is a new term to me and it is not on the illustration http://www.kerisattosanaji.com/kerisdiagram.html that I use most frequently
thanks
