A utility knife includes a handle having a blade track system with a pivot point and a blade mounted in the blade track system. The blade includes a cutting/scraping edge extending along a side of the blade. In an implementation, the blade is shiftable between a closed configuration, where the cutting/scraping edge is enclosed within the handle, to a first open configuration, where the blade extends longitudinally outward from an end of the handle. The shift between the closed and first open configurations can occur by rotating the blade about the pivot point and in the blade track system. Also, the blade is shiftable along the blade track system between the first open configuration and a second open configuration, where the blade is located towards another end of the handle such that the cutting/scraping edge extends downwards from a bottom of the handle. |
