I daily carry a custom made leather pouch with a leatherman holding a... 3" max blade, an opinel 3-1/4" folding single edge skinning knife, and a tactical flash light. Also a folding razor knife to cut boxes....
Am I breaking the law?
HI's knife laws are fairly lenient. What you described is legal. That's not to say if you were involved in a defensive stabbing, you'd have an easy day in court. There's no such thing in the Aloha state.
A leatherman and a box cutter are considered tools because their intended design is a tool. The double edged, automatic, butterfly stuff, ect... is a no brainer. The questionables A Katana is a designed weapon- NO GO. A Marine Fighting Knife "KA-BAR"- Fighting is right in the name....
I carry Emerson Knives all the time. By description they're all perfectly legal. HOWEVER, if I ever had to defend myself with one, I'm sure the fact that CQC is in the name and Bad Intent being all over the Emerson website would come up in court. Will that stop me from carrying Mr. Emerson's very fine cutlery products? NOT ON YOUR LIFE!!!
But like someone before stated, if you are truly concerned, ask a lawyer.
