What Knives Are Legal to Own In Pennsylvania?

The following knives are legal to own in Pennsylvania:

  • Pocket Knife
  • Bowie Knife
  • Butterfly or Balisong Knife
  • Penknife
  • Any kind of Hunting Knife
  • Automatic Knife (for lawful purposes)

The term “offensive weapons” which used to cover certain types of knives has been amended, removing knives and other cutting instruments from this category.
