Back when I used to be a chef, my most important tool was a Chef's knife. The Wusthoff and Henkles and rando knockoff knives might look pretty similar, but I could tell just by looking at it if the spine side of the tang was a bit too short and would give my index finger blisters, for example. It didn't have to be perfect, but it had to work for me.

As a full-time developer, I was working with text editors just as many hours per day as I worked with my chef's knife. Using a text editor that doesn't meld with the way I do things is incredibly frustrating. I do most of my dev work in Unreal Engine these days so a nice, performant editor that was as smooth as other paid editors would get my greenbacks.
