A utility knife is useful for operations such as glazing, roofing, carpeting and sheet rock fabrication wherein the knife is used in close proximity to window edges, walls or corners. A blade-holding portion of the utility knife has a planar bottom wall and structure for mounting the blade at a small angle relative to the bottom wall so that the blade is able to flex and substantially conform to the plane of a surface upon which the planar bottom surface of the utility knife is supported. A handle portion of the utility knife is offset from the planar bottom surface so as to position a user's hand away from the surface on which the utility knife is supported.
