Made by Baduy whose father used to be an apprentice of well-known blacksmith in their tribe. He said to me that this is the only "gobang" that they know.

Differences with the common golok are on the notch, bolster, and the shape of the gado.

Lately, when i was looking more information on wedung. I found, "wedung sanibin". Sanibin is the name of empu (mastersmith), from the foothill of Semeru Mountain. Those two mountains (Bromo and Semeru) just around 70km in distance.
The shape of wedung sanibin's blade is similar to the Tengger's, with variations on sheath and hilt, however there are sheath and hilt that are similar to the Tengger's.
It said that the Lumajang (Lamajang in the past) where the wedung sanibin comes from initially inhabited by people from Madura. Definitely different from the cultures of Tengger.

amazing !
and so many Indonesian collectors here and still unknown ?

Time to pay a visit to the vulcanic Bromo area and Semeru national park,gents
;)!

Tengger greetings
