Description: |
| A folding pocket wrench with multiple open end and box sizes suitable for bicyclists. The combination could include screwdriver blades. The blades have interlocks and alternate screw or clamping lever tightening means so the effective working leverage on any of the wrench openings is doubled. Springs between the blades separate them for easy movement when the tightening means is relaxed. |
