NO.
MGL c. 269, s. 10(b) prohibits switch blades, ballistic knives and holsters that open a knife as it is drawn. It does NOT constitute a blanket prohibition on carrying knives.
I demonstrated a Kershaw assisted-opening knife in front of:
1. An Assistant Attorney General,
2. TWO EOPS attorneys;
3. A Chief of Police; and
4. A State Police lieutenant.
No-one fainted, nor was I seized, arrested, detained, charged or otherwise interfered with. And I left with the knife.
SOME cities and towns may have ordinances, most likely prohibiting sheath knives and/or knives over a certain length.
I miss You!
