Utility cutter

摘要

A knife includes a handle that includes a gripping surface; a blade slide positioned in a recess of the handle that extends from an opening of the handle through a cavity within the handle; a blade coupled to the blade slide near a proximal end of the blade and extending through the recess and into the opening when the blade slide is in the retracted position; and a guide coupled to the blade near a distal end of the blade opposite the proximal end, the guide including a contoured surface configured to engage a workpiece to extend the blade slide a distance from the retracted position to an extended position such that the blade is extended from the opening of the handle, the blade slide biased to move from the extended position to the retracted position.

1. A method for slicing a material, comprising:
engaging a material with a guide coupled to a blade of a utility knife near a proximal end of the blade, the blade coupled to a blade shuttle near a distal end of the blade, the blade shuttle positioned within a housing of the utility knife; extending, through engagement of the material with the guide, the blade a distance away from the housing from a safe position substantially enclosed within the housing to a cutting position substantially out of the housing, the blade shuttle biased to move the blade from the cutting position to the safe position; engaging the material with the blade to slice the material; and based on a user of the utility knife disengaging the guide or the blade from the material, urging the blade shuttle to move the blade from the cutting position towards the safe position by a biasing member coupled between the blade shuttle and housing.
