Hi Flavio,
Congrats... I really like the Pedang..
..the influence of Hindu weapons seems unmistakable with the example you've posted. The hilt is great (very Khanda-ish) and the blade looks fantastic.
The blade on the Gurade is also very nice.....is it European ?
My knowledge of SEA weapons could be written on a postage stamp.....but the blade on the Mandau seems quite modern, the hilt has very little wear or patina. (yesterday I posted a recent Mandau.....functional, well balanced and basic with a good forged blade...but 40+ years old)
Regards David
