warangka for identification

[Gustav]

David, at the moment it's in my hands.

Jean, as David already wrote, such Tikel Alis and similar elongated Greneng can be seen on S-Sumatra blades. S-Sumatra blades tend to be smaller, but I know of some quite large specimens.

What is absolutely out of norm for S-Sumatra on the initial blade is the Mboto Rubuh Blumbangan.

As you can see, the edges ant the tip of the blade have been cleaned and treated with warangan. This must have happened already a while ago.
