My wife is from Costa Rica, so I've been there a bit. After a few trips I figured out that I had to have a small machete to open coconuts with. Coconuts are everywhere and are yours for the taking at many resorts. The slightly sweet water inside is pure, delicious and there's about 8oz in each nut. But, they are real hard to open without a machete. The machete is perfect for this job. Anyway, so I find a machete vendor en el Marcado Central, and get a nice light, short one (travel model) with a comfortable handle and a handmade well fitting leather scabbard. For cheap. It's my favorite machete. It's an IMACASA brand made in El Salvador. Here's their websight. http://www.imacasa.com/Machetes/machetes.html Click on Models to see their many varieties of machetes. You can bet that these things get used down there too. Next time I go to Costa Rica I'm gonna get me some more machetes (of various brands) to start a little collection. 
Darn! I wish I had some coconuts!
