How do you upgrade tools? I heard you can but I'm not sure how. Anybody have a link to a guide or information on it?

You buy the blueprints at the trade depot vendors and make them. You can find all information you need here http://fogu.com/sos1/basics/tools.php

Silk Country will sell the watering can and hoe upgrades. Kind of sucks that the other tools require gold as the 2nd step.
