(I don’t leather craft, but I do plenty of other craft and engineering things.) I used to be pretty stingy about changing blades until I bought a 100 pack. Now I happily change the blade when I feel it getting dull or when I’m starting a new project. I’m ok with having to go over a cut a second time or so, but when the blade is dull enough it’s making the cut less clean, it’s definitely time to change.
Eh, I also enjoyed seeing the comparison between Go and Python, seeing the jumps in time because of allocations, and knowing the size of the list when the more efficient algorithm started to become faster.
