Pocketknives are better than nothing, but it takes practice to be able to reliably open many of them one-handed under zero stress, let alone during a physical altercation. Additionally, the locking mechanisms for folding knives require secure engagement and a full and complete opening to work properly. Without opening completely, and seating into the locking mechanism, a pocketknife can fold shut on the user’s hand in a struggle. For this reason, although more difficult to conceal, a single-edge fixed blade would be preferable to a pocketknife for women or men. These tend to draw more attention in a casual or work environment, and are more difficult to conceal, if legal and desired (state and local laws vary on the size of knife one can legally conceal. Please check your local laws or contact the U.S. LawShield Independent Program Attorney in your area).
