Spyderco slipjoint knives: traditional lock with a modern look and feel
Spyderco slipjoint knives are a cool, modern interpretation of an ancient concept. Slipjoint pocket knives belong to some of the oldest designs in the world. For over hundred years pocket knives without a real lock have been produced worldwide. A slipjoint lock means there is only some resistance to prevent a knife from closing. This is not a complete lock. Because it doesn't completely lock the knife, slipjoint knives are legal in many places in the world. Great because laws do change sometimes.
