Well done Lew,
checking on the Arit, I found a Balinese site which stated Arit (sickle). Then I found this about the Arit and several other tools...
"...The items shown below are not really weapons, they are tools, however, when disputes arise
today and the people involved feel that they need to settle these disputes with violence, these
tools are the implements most used as weapons. In fact, in Central Jawa today it is probably
correct to say that more people are killed and wounded with the type of tools shown here than
with any other form of weapon....."
However also on this site is this a Celurit from Madura listed as a weapon.... picture below
