Wos wutah & ngulit/kulit semangka are both simple random pamors.
WW can have many layers of contrasting material, and during the process of making there can be surface manipulation.
NS has far fewer layers of pamor, and there is no surface manipulation.
The end result for WW can be a tightly packed, random pattern.
The end result for NS has far fewer layers of contrasting material, the naturally occurring indentations during forging result in exposure of contrasting material when the cold work is done.
So, with these simple, random pamors you don't really have a lot of choices, if in doubt you just run through your possibles and eliminate one by one, if you've seen a lot of NS examples, or WW examples one glance is normally sufficient.
