What Self Defense Weapons Are Legal In Massachusetts? Massachusetts has some restrictions on self-defense weapons compared to other states. Here's a breakdown of what's legal:
Pepper Spray: Unlike some other states, pepper spray is legal for purchase and possession in Massachusetts for anyone over 18.
Knives: Folding knives with blades under 2.5 inches are generally legal. However, there are restrictions on other types of knives, including:
Automatic knives
Ballistic knives
Double-edged knives
Important things to remember:
Local ordinances: Even though something is legal statewide, some cities and towns may have additional knife restrictions. It's always best to check with your local police department.
Self-defense laws: Massachusetts law allows using reasonable force for self-defense. The key is "reasonable" - you can't use excessive force.
