I carry two of my tool bag.

I have one huge industrial strength with replaceable retractable brake off blades.

Then I have one that’s really small like the tiny plastic ones, but it’s Even thinner and slimmer the case is metal.

And I have maybe half a dozen other random pocket knives.

Honestly ever since I got a Kershaw Static, I don’t really use box cutters anymore. The blade shape is just perfect for the job and it stays sharp for ages
