I noticed my toothbrush. I tend to brush hard, so I go through toothbrushes quickly; the bristles were all splayed out rather than straight. Wizard power would be making my own toothbrush, out of something which wouldn’t wear out so easily.
They do make various different firmnesses of toothbrush.
In general, there are large economies of scale from mass production. Society needs to be seriously screwing something up before making it yourself is a viable option for a lot of things. You can make your own toothbrush as a hobby, but it will probably be cheaper and easier to just buy more toothbrushes. Or, run hot water over the bristles, squeeze them back into shape, then run cold water over them. Or just keep chewing on a flat looking toothbrush.
(Also, you want your toothbrush to be less wear resistant than your teeth, as your toothbrush is easier to replace)
Wizard-power is pretty weak when you are just making something for yourself. It only really shines with economies of scale. Some of that economy of scale is in owning the tools. Some is in understanding the particular details of the domain.
