Why bother to bring anything more than a pesonel pocket knife?
If you need something more, buy what you need from the local economy and just use what the locals use. When we went on our Costa Rica rain forest trip we just took our sak's, and by chance that is what the local guides carried in combination with small machete's of Tramontina and other brands. Our son John, who was in South Africa on buisness for his company for some months, bought an Okapi localy and it blended in with what the locals used.
Leave the fancy knives, watches, and other American luxury toys home and blend in with the local people. You'll make friends faster, and you may even have the experiance of finding out you don't need a 200 dollar blade to get by. Besides, when the locals see you using and getting by with the same stuff they use, there is alot more respect for you, and through the friendship that will develope, you'll see alot more of the real people and the local culture. And local friends wil keep you from being ripped off by those who think all Americans are rich. When John was in the the Phillipines for 6 months he rode a Honda motorscooter like many of the locals. When he went to have it serviced at a local mechanic, his phillipine friend followed him over to drop it off and give him a lift back to work. An argument took place when his friend saw what the guy was going to charge John, and it was almost double what it should have been. After alot of jabbering back and forth, the mechanic relented. On the way back to the office the friend told John the mechanic saw the high end watch on John's wrist, and told the native phillipino why not charge him more, he's rich and can afford it.
When you're not in the U.S. of A. anymore, blend it. Blend in.
