You're welcome Johan.. :)

This type of blade can be found in Peninsula, Sumatra and Sulawesi. However I am inclined to say that it is peninsular due to the greneng. But, I cannot provide any evidence for this. In other words, I would rather keep it to myself. IMHO the safest description is probably "A Bugis Keris" - a very open description. The narrower the description, the higher the chance that it will raise questions.

The tip looks like it had been filed. You can see towards the tip the baja area is shiny with no pittings/erosions like other part of the blade. Also, it looks a bit off. Probably the tip was broken in the past. Not much, probably around 5 mm.

Frankly Johan, from my perspective, it would be more of a shame if this keris still had a broken tip that was not reshaped. This stuff does happen from time to time and it is acceptable in a number of keris cultures to reshape a blade when it is necessary. ;)

Much obliged, David & Rasdan!
