<p>A double-ended dual mechanism retractable blade utility knife (10). The knife (10) includes two separately actuable mechanisms (382, 386) which allow extension and retraction of one or both blades (28, 34) independently of one another. The cutting surfaces (30, 31) of the respective blades (28, 34) are oriented towards opposite sides of the knife (10), thereby facilitating rotation of the knife (10) within the user's hand in order to change which blade (28, 34) is currently being used. The independent nature of the dual mechanisms allows both of the blades (28, 34) to be held in the extended position. A storage area (72) is further provided behind each of the mechanisms for the storage of spare blades (29).</p> |
