| 摘要 |
A double-ended dual mechanism retractable blade utility knife. The knife includes two separately actuable mechanisms which allow extension and retraction of one or both blades independently of one another. The cutting surfaces of the respective blades are oriented towards opposite sides of the knife, thereby facilitating rotation of the knife within the user's hand in order to change which blade is currently being used. The independent nature of the dual mechanisms allows both of the blades to be held in the extended position. A storage area is further provided behind each of the mechanisms for the storage of spare blades.
