 Antique kalis (kalis made before 1930) were made with a separate gangya (guard) like their Malay cousins, while more modern made kalis lack this feature and have gangya that are in fact integral to the blade.Some newer kalis do have an engraved line to simulate the appearance of a separate gangya, but when inspected closely it is evident that this is only a cosmetic engraved line, and not a true separate gangya.At some point near the early 19th century, gangya started to be made with a distinct 45-degree angle near the terminus.
