> mixture of molds and being broken in Unused new-old-stock MX switches from the mid 1980s have noticeably smoother feel and don’t make the scratchy sound you get with new MX switches from, say, 2010. Artificially wearing in keyswitches with 100s of thousands of robot keypresses seems really silly to me, though I guess it’s easier than disassembling every switch and sanding down the friction points with fine-grid sandpaper or applying fancy aerospace lubricant or whatever the kids are doing these days. YMMV.
