Congratuations Gav. I am glad that you finally got the "expert" assessment that you have been wanting on this piece. Funny thing about "experts"....if we look long enough we will always be able to find one that will tell us what we want to hear. I am not trying to say that you latest "expert" is not absolutely correct. He may well be. Personally i know nothing about these knives and to me it looks quite nice. But as someone who has spent a lot of time collecting and learning about keris i have discovered that things are not always what they appear to be and sometimes people deliberately create things to deceive. Not necessarily the case here, but always a possibility.
Many of the people on this forum who have taken the time to try to answer your questions about this piece have a great deal of combined knowledge about these knives. Some have made it their specialty. Doesn't mean they are right about your kindjal either, but they didn't have to respond to your post, they have done so with good will in the spirit of collecting and sharing knowledge. You might do youself well not to alienate an entire community of knowledgeable collectors just because you found an expert who told you what you wanted to hear.
