Multi-purpose utility tool

A utility knife comprising:

• a blade mount component configured to accept a blade, said blade mount component comprising a square boss having rounded corners and a first width;
• and
• a guide track component comprising a rectilinear slot having parallel sides, said rectilinear slot comprising three portions:
• a first portion having a second width, a second portion having a third width, and a third portion having a fourth width, said second portion being located between said first and third portions,
• wherein said square boss is operable to slide within said rectilinear slot and thereby allow said blade mount component to be slidably attached to said utility knife,
• wherein said second width is sufficiently larger than said first width to allow for linear movement of said square boss within said first portion and said second width is sufficiently small to prevent rotation of said square boss within said first portion,
• wherein said third width is sufficiently larger than said first width to allow for rotation of said square boss within said second portion and to allow for linear movement of said square boss between said first portion and said third portion, and said third width is sufficiently small to limit movement of said square boss between said first portion and said third portion to an essentially linear movement,
• wherein said fourth width is sufficiently larger than said first width to allow for linear movement of said square boss within said third portion and said fourth width is sufficiently small to prevent rotation of said square boss within said third portion, and
• wherein rotation of said square boss corresponds to rotation of said blade mount component, thereby permitting rotation of a blade affixed to said blade mount component.
