Yup, tourist junk - I'd gladly take it off your hands, and even pay the shipping cost for a parcel from PR.
Now seriously, all of the items appear to date back to at least the 19th century and to be of above average quality, and certainly meant for use within the culture. Defeinitely not souvenirs.
You might want to try etching the blades as there is a high likelyhood that they may be made of wootz.
I wish I did this well whenever I bought things, which I knew little about.
