Costa Rica knife laws?

[supertac916]

I'm heading to Costa Rica next month for a week vacation and plan to check out the various sceneries, including checking out the rainforests. Anyone know the laws out there in regards to fixed or folding knives being carried? I'd like to bring a 4" fixed blade for the hikes and a Benchmade folder to carry around in my pocket. Appreciate any insight or links.

Thanks!!
