 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.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.
