I do IT/computer repair so my post probably isnt exactly the most relevant. Tend to do more breaking zipties and opening amazon boxes instead of stabbing holes in walls. :)

The people i work around are pretty sheepy and cant conceal dike/daggers or "spring" opening knives in my area due to state law. ordinary pocket knives up to 4.75in are okay to conceal or anything as long as its carried openly and is distinguishable.

That being said i carry the gerber prybrid-utility knife. Also carry the spyderco dragonfly (pink, s30v modal,) roadie, 20cv wharncliffe delica, and the g10 para 3 modals. The spyderco shaman and pm2 sometimes find pocket time depending on the stuation and whats going on
