Kalimantan and Sulawesi, where it is known as sundang, sondang or keris Sulu (not to be confused with the súndang, another native Philippine sword from the Visayas). Physical description Blade The kalis blade is defined as one that is wide on the base and double-edged. It is capable of delivering both chopping and slicing cuts. While many assume the traditional form of the kalis is the fully wavy blade, the half-waved half-straight, as well as the fully straight blades, are equally if not more common, as straight blades were more practical in combat. Moro kalis blades generally range in size from 18 to 26 inches (46 to 66 cm), though as with all Moro weapons there are exceptions. Generally however, the larger blades are found on later pieces, while the oldest Moro kalis tend to be of smaller stature. Damascene patterning is sometimes evident though often not as controlled as seen in the complex pattern welding of the smaller Malay keris. Guard (gangya) The gangya (guard) of a kalis blade is made in such a manner that their lines flow very elegantly into the blade, never interrupting in continuity from transition from gangya proper to blade. 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. Opposite the hook-like fretwork on the gangya, exists a curved cavity. It has been suggested that this cavity is representative of the trunk of an elephant, others contend that it is the mouth of the naga (serpent) with the blade being the tail, and still others contend that it is in fact the open mouth of an eagle. Modern tourist kalis blades can be distinguished by a number of features that once identified are quite easy to spot. Perhaps the easiest to identify feature of a modern tourist/fake kalis blade are the shaping of the waves. Traditional kalis feature gracefully undulating waves that are forged deep into the blade to
