Description: |
| Intended to be as close, in appearance, as possible, to conventional screwdrivers, this ratchet handle can be set to drive in either direction, or both . The settings are effected by slight turns of the knurled sleeve below the ferrule, while various blades/tips can be used interchangeably. |
