Chefs tend to be gear addicts in my experience.

The unitasker advice is also a bit difficult for inexperienced people to follow, from what I've seen. A stand mixer is a great multitasker on paper, whereas a speed peeler does exactly one thing. Yet the latter will be used massively more often than the former in most kitchens. Probably the most used tool in my kitchen (after knives and cutting boards) is the kettle, another unitasker.
