Fewer gadgets and smaller batterie

JustCharlie posited “fewer gadgets and smaller the batterie the better.” While I’m blessed with too much nice stuff, I’m inclined to agree. As I look around the room and take note of what I actually use a lot, it’s a fraction of what’s here...two CS pans, the medium saucepan, the 6 qt. Casserole (not the LC), the stock pot, the chinois, the large gyuto, the nakiri, and sometimes a paring knife, tongs, a sharp spatula, wooden spoons, a flat whisk, a colander, two medium mixing bowls, a sauté pan, jelly roll pans, a silicone spatula, oil crusts, a salt pig, a pepper grinder, a large cutting board, and coffee equipment gets me through 95% of what I make. I have a few specialized things that get more use around the holidays, but I could probably wire around them. My wife uses the KA and the FP way more than I do. Despite my reliance on these things I make a point of using everything I have at least once a year...Madeleines, tart tatin, poached fish, Bernaise in a double boiler, pate en croute...but I don’t go out of my way to use the specialized tools if other things are just as quick and easy. For example I can make pommes Anna in a skillet, slicing the potatoes with a knife or I could use a mandoline or the FP. The knife or mandoline is quicker and easier than the FP with easier clean up. What are your experiences in this regard? Do you agree with the original premise? Are there things you use rarely but still would want to have, like a balloon whisk for egg whites or a slicing knife for roasts?
