  • What’s the difference between an assisted opening and an automatic knife?
    Many times, spring assisted opening knives are confused with automatic knives. A spring assisted knife’s natural position is closed and an automatic knife’s natural position is open – the blade is being held in a closed position by tension. When you open a knife and there is no effort involved except for pressing a button to deploy the blade, it’s an automatic. Click here to shop our selection of assisted opening knives.
  • What’s a switchblade knife?
    A switchblade is just another name for an automatic knife. Although an automatic opening blade can also be deployed from the side of the handle like other pocket knives, the automatic knife that most folks are familiar with is the out-the-front model. Click here to shop all of our OTF knives.

  • Are automatic knives legal?
    The answer is, “yes” and “no”. Every state has their own laws regarding the possession of automatic knives. Before you set your heart on a switchblade, make sure to check your local and state laws about owning one.
