Come to Mass., like Smash05 wrote, no length limits here unless you visit Boston. Western Mass. has a culture of hunting and camping, so I don't worry about how I look wearing a sheath knife. People seem to be used to it, and if I'm camping/hiking, I'm dressed for it and don't come across as a criminal. You might even have an easier time getting a Mass. resident carry permit than a NYS carry permit, depending on your NY county.
