Of course you come to Bay Area Bites for all your Bay Area food needs. But, we (unfortunately) don't offer kitchen items for sale and we can't help you find the perfect pineapple de-corer.
Yes, we suggested a number of items that most serious amateur chefs should have in their kitchen. And, in the process of researching those kitchen gadgets, it became clear that amateur chefs also need to know where to get the items they need to elevate their kitchens.
In that spirit here are some kitchen sites you should visit before you start purchasing willy-nilly:

Williams-Sonoma and Sur La Table: These two are kind of the granddaddies of high-end kitchen stores. You can be virtually guaranteed that, if you're willing to spend the money, you can find any kind of kitchen gadget you could possibly want at Williams-Sonoma or Sur La Table.
Williams-Sonoma, of course, does many things besides kitchen items and also owns West Elm and Pottery Barn. Sur La Table, with just 100 retail stores to Williams-Sonoma's 560, specializes in "the art and soul of cooking." Either is a great place to start when looking for an obscure kitchen tool that you simply can't live with out. And, the added benefit is that, with physical locations, you can always visit to test out how that zester really fits in your hands.

Provisions by Food52: Sure, Food52 started as website for cooks to read and talk about food. But, this past August, Food52 launched Provisions, which combines recipes with a catalog to buy the things you need to make the delicious-looking dishes in the pictures. The products are organized in collections like "European Pastires" or "A Long Winter's Night" or the practical "Cleaning."
