Before I got into MTs, I would occasionally forget to throw my Pinchy and Explorer in my back pocket before leaving to work. Like you, it would leave me feeling naked. I would reach for it all day, like a ghost limb
After I got into MTs, I started leaving a backup MT, SAK, and light at work. But, I am fortunate, as I have a safe place to stash a small pencil box of goodies. The box contains an MP600 (which is fine in case I forget my main carry), a worn out SAK Explorer, an old incandescent maglite, extra batteries, toothbrush/toothpaste, allergy meds, and other routine medicines I have to take daily. A nice "Just in Case I forget anything" pack.
Since I began doing that, I haven't forgotten my tools or meds. But, being 20 miles from home, it is nice to know my daily routine will be similar/the same, because of the stashed box.
