Th232, the Assist does not have a sharp point so that when you cut the seat belt you don't stab the victim. Take a looksee at the Assist, no point. The police, the courts would not mind it. The serrated cutting blade would be about the same length as the folder. The steel should be H1 steel.
Police in my jurisdiction would charge you with CCW for carrying a concealed sheath knife. Heck an open box cutter in a sheath under your coat is CCW. If you had a fixed blade exposed it would be Inducing Panic. Don't even get me started on serrrated knife perception. I have often wondered where people who carry fixed blade knives go. Farm or Field is about it for non police in Ohio. IMHO it is not worth the risk. Here is a good one.......I CAN carry a pistol with a CCW permit in my city but I CANNOT legally carry a fixed blade knife.
I would go with the Pacific Salt knives with yellow handles and non serrations for all of your on-person traveling knives. Sharp, easy to maintain, easy to see if you drop, and any cop can see them from across the room. It also does not have much of a point so would do decent double duty as a rescue knife. If you have a fixed blade it should be in a pack on your bike, not readily accessible if you are crossing jurisdictions IMO. I still think you ought to have a Victorinox swiss army knife with you though. Those tweezers, scissors, and thin keen blades are hard to beat for splinters, blisters, and minor "surgery". A Victorinox Classic would be very useful and is very tiny, I would attach one of the little LED lites too it as well. Happy hunting.
