The complete process lasted two hours. Two different types of arrows were prepared. The most frequently used is the traditional one with the wood tip. In the last few years, Mentawais also started to make a triangular metal tip to hunt wild boars. The poison is very efficient, it kills boars or deers almost instantly.
Monkeys are much more resistant and can live up to five minutes.
Thus dogs are used to recover the monkeys. Those are sharp, not very precise and easily cut your fingers. The Mentawai strings are pieces of art. They might not be a match to kevlar strings used in modern archery, but they aren't far behind and are easily made in the jungle from braided tree barks soaked in a resin mixture. They remove the bark of the tree and separate the inside layer of the bark from the bark itself.
