Nailed it. Don't hide it, don't threaten, and you're good.We chuckle, but before Sam Colt made men equal, tomahawks/ hatchets , and big ass knives Were sidearms. Pistols were too unreliable and single shot at best, swords and muskets were cumbersome for constant carry. ( And knives and hatchet equivalents had usefulness as everyday tools.)
But at the OP's inquiry, tomahawks/ hatchets are not enumerated in 4-101 as *Extra Evil* , so they would be treated the same as fixed blade knive, axes, hammers, chain saws, swords, etc.
Don't conceal them . Don't commit felonies. Don't traffic CDS. Don't have intent to ( kind of varies in case law). Be cognizant of possible ambiguity between transported in vehicle, and carried concealed in vehicle.
