Yes, indeed.
To be even more provocative, some kerises are not good enough for the social higher strata, and at the same time, they make poor weapons too. So what do we make of these kerises?
"Old" not equals "good" or "bad"
"New" not equals "bad" or "good"
Likewise for "simple" and "complex"
But I think we have digressed a bit frm the original point I wanted to make, but I suspect was not conveyed adequately - that a "kampung" quality hilt does not adhere very strictly to archetypal forms. You get all sorts of variations and unusual features. From my experience, it is usually a futile exercise trying to classify these examples definitively. Sometimes, they are just amalgamations of influences and even the whims and fancies of the maker.
So this is to be read in relation to your question/statement - this looks like a tajong, but is actually a coteng.
The first rule of collecting is to collect what you like. Happy learning about the keris, and then collecting it!
