Age to carry a knife?

I'd say under 3.5", but I'm no lawyer/doctor/black smith.

Somewhere I saw the 3.5 inch rule in writing. I ground a bit off my Buck 110 so it wouldn't be an issue. A cop in Aurora measure my Gerber a few years back, he was making sure it was under 3.5 inches.

It is legal to carry concealed a push knife if it is less than 3.5 inches.
IT IS LEGAL TO CARRY CONCEALED A PUSH KNIFE IF IT IS LESS THAN 3.5 INCHES.

In the case A.P.E vs People in 2001, it was found that a knife that is less than 3.5 inches is not a weapon if the prosecution can not prove that the person intended on using it as a weapon. In the case, the defendant was found with a push knife that was less than 3.5 inches and the police charged him with unlawful carry of a concealed weapon. The prosecution could not prove that he intended to use it as a weapon and he was found not guilty of the charge.
