Abstract
A folding knife includes a lock blade and a handle. The handle includes a transfer bar assembly and a blade opener spring. When the lock blade is closed, a spring working in conjunction with the transfer bar assembly biases the lock blade closed. When the lock blade is opened past a certain point, a blade opening spring assists in moving the lock blade into its open locked position.
