Well, I can dress casually, in jeans, at work, but I'm thinking more in terms of reducing bulk.

Also, with even bus security increasing, and passengers everywhere being forced to empty their pockets, everyone will know what you have.

There's no being low-key anymore. What's the use of carrying a SAK deep in your pockets when someone will see it and declare it a weapon? Especially since no one will tell you what is and is not a weapon.
