Abstract
A utility knife/box cutter includes an ergonomically-shaped handle portion with exterior stippling to provide a good grasp upon the knife. Within the handle portion, a channel member is received in a forwardly extending cavity and movably receives a cutting blade carrier for longitudinal movement relative to the handle portion. A cutter blade carried in the blade carrier is moveable between a storage position entirely within the handle portion and successively further forward use and replacement positions. Also received into the handle portion is a spare blade holder member pivotal between a blade retaining position entirely within the handle portion and a blade releasing position in which a forward part of the spare blade holder member is pivoted out of the handle portion to present spare blades for removal and transfer to the cutting blade carrier.
