Do you mean a Stylus? A stylist cuts and dyes your hair.
Anyway, here's my list. I use what I like to call a matryoshka packing scheme. I'm a dude so most days it's all contained in pockets, I have a small bag/pouch for when I need more space, and a slightly bigger one that fits in a backpack and can also hold the smaller bag.
Always on me:
-Phone
-keys+Gerber Artifact multitool on keychain
-pen/writing pad. Usually Rhodia or Rite in the Rain. I have a tac pen with a glass breaker and handcuff key in it.
-Handkercheif(s), I like the salt-armor mask thingies when the mask restrictions were going on.
-Wallet+standard wallet things+metal eraser guard+basic lock pick set
- Kershaw assist-opening knife or a utility knife if I know I'm fucking with boxes
Slightly bigger bag:
-Bigger/more writing pads
- Clip light+small/powerful LED flashlight
-more pens/pencils, usually incluude my 6" machinist scales, picks, and a carbide etching tool
- Charger pack, cables, wireless headphones
Murse:
-All of the above
- Springfield Armory Subcompact S&W.40
- Extended magazines
- ESEE Izula
Almost all of my bags/pouches have velcro somewhere so I can be stylish with my small collection of very autistic patches.
Edit for forgotten things that migrate as needed: Business card case, cigarette case, folding mirror (all brushed stainless and minimalist). I haven't smoked cigarettes in a long time but for vaporizer(s)/weed the cig case works well. I also have a couple different multitools from Gerber and Leatherman. I also have some small pick/file sets. The diamond files are also the best damn nail file you'll ever use.
