People often make much of the difference in weapon laws between England and America but, as far as blades go, the two are broadly similar, at least in Kentucky.
Kentucky law allows me to own all the blades in my collection; so does England. Kentucky law allows me to display them in my home; so does England. Kentucky law prohibits me from carrying them in public; so does England.
Well, with two exceptions. Kentucky state law makes it a crime to carry a knife in public unless it is (a) "an ordinary pocketknife" (like a Swiss Army knife or similar) or (b) a hunting knife.
That (above) is a hunting knife. It is 13" long with a 7" single-edged blade. The top of the blade features a false edge. The Bear's head ornamental crosspiece and pommel are brass, which make the knife fairly weighty. The handle, disappointingly, is plastic, but could easily be replaced with something more hard-wearing by a bladesmith.
Kentucky law does not define exactly what a hunting knife is, but by the generally accepted definitions, this qualifies.
So it's legal to carry.
Whatever the law, any police officer who found you carrying this could be forgiven for asking just why the hell you have it, unless you were actually engaged in a hunting trip.
