Henk and Marcokeris, thanks for posting these examples. I agree with you Henk that these "soldier's keris" are in a different catagory to what we often think of as a "tourist" keris, although i don't particularly like the term "tourist" keris in general as it is usually only meant to describe low quality keris, some of which might actually serve some ethnographic service such as a part of wedding attire and not actually be meant for export.
I have seen these "soldier's keris" in all levels of quality and i think they are certainly important in the overall history of the keris. I wouldn't mind finding a good example one day for my own collection.
However, i still fail to see how Naga Sasra's keris is in any way "equal" to these "soldier"s keris" other than the fact that they both have carved sheaths. I see no similarities here.
