Thank you HeavyHanded! This is very interesting to read.
To tom19176 - yes, " possesses any dangerous or deadly weapon and is not a citizen of the United States " is the concerning part. I heard non-citizens (e.g., green card holders) can legally possess certain guns in NY state. Since guns are certainly deadly weapons, doesn't it mean it's contradicting with the quoted knife law here?
You are welcome - I hadn't been aware of that language prior to your question, so a good learning experience. NY knife law is so arbitrary sounding, but outside of NYC, pocket and belt knives are ubiquitous and unlikely to ever get you into trouble of and by themself. - NY is largely rural but you'd never know that without living here or visiting Upstate.
There's a number of things wrong with this law as applies to knives - at least knives that otherwise are legal for citizens to carry. Firearms aside, it is illegal to carry
any knife as a "weapon", and if carried for legitimate utility use (IE, person in possession isn't apprehended committing a crime or declaring that their knife is indeed a "weapon"), said knife is a tool and not a weapon anyway.
Whether a knife is a dangerous knife is not really settled as far as the courts go and winds up case by case. Currently it may be determined on the basis of three alternative considerations:
one, its own characteristics which show that it is primarily intended for use as a weapon (looks !!??);
second, a modification, which converts what would otherwise be a utensil into a weapon (don't sharpen a screwdriver or piece of tempered glass);
and third, the circumstances of the possession which may reveal that the possessor considers it a weapon and not a utilitarian tool (don't be heard yelling things like "I'll cut you DEEP!" or telling an officer you carry it because you get scared sometimes. If asked whether you have a weapon, the answer is no. If being patted down or taken into custody and asked if you have a weapon, the answer is still "no, but I do have a knife for utility use" or some such.
The current standard is based on overall dimensions and possessor's other circumstances - a concealed 14" blade, attempting to conceal a knife after being chased by police for threatening someone. The most troubling is a juvenile that was found to be in possession of a weapon for having a case-cutter in his pocket when arrested for pot possession. The crazy thing is if he had been carrying a small folding knife, it might have gone the other way as there had been a rash of case-cutting attacks around the time of the arrest.
On the other side, a man who had an oversize hunting knife on his belt in his home when it was raided by LE for narcotics, was found to be legal possession - not a weapon.
