Hi Ferry, even though Alan said that this keris can be classified as Tuban blade based on photograpgh but he also said that his opinion can be changed easily if he handle the blade, so it sounds possible if the tangguh change from Tuban to Blambangan
. To my eye, low and slanted gandik, probably its skewness, when I refer to another Blambangan blade which is owned by my friend, I can say that this keris looks like it. For me, I am not confused with tangguh matter, since I like it, I will keep it. Anyway, thank you for your information.
