A utility knife and methods for using the same are disclosed. The utility knife includes a handle portion, a head unit attached to the handle portion, and a blade attached to the head unit. The handle portion is made of two parts jointed together by a hinged connection arrangement. A blade support component is also included which orients the blade in perpendicular relation to a central axis of the handle. The exemplary utility knife can safely be used in many applications with a design configured to help prevent user contact with the blade's cutting edge or edges.

The handheld cutting tool variants disclose improvements to the handheld cutting tool of U.S. Pat. No. 11,426,888B1/application Ser. No. 17/704,935. The handheld cutting tool variants deploying a razor blade have enhanced cutting made possible by either modifying portions or eliminating portions of the blade holder nosing which in turn is made possible by deploying either one of two newly disclosed blade restraint mechanisms. As with application Ser. No. 17/704,935/U.S. Pat. No. 11,426,888-B1, the tool is comprised predominantly of a handle body, a blade holder assembly which serves to deploy and constrain a replaceable blade and a rotational control assembly actuated by the user that enables the blade holder to rotate between retracted and a plurality of extended positions.

A system may include a blade die, a first clamping caul positioned on a first side of the blade die, and a second clamping caul positioned on a second side of the blade die. A molding surface of the blade die and a molding surface of the first clamping caul may be configured to bend a first interchangeable blade positioned therebetween into a first shape in response to a first compression force. A second molding surface of the blade die and a molding surface of the second clamping caul may be configured to bend a second interchangeable blade positioned therebetween into a second shape in response to a second compression force.

A device is disclosed including a reloadable utility knife having a blade magazine with one or more compartments for storing multiple cutting blades. The blade magazine has a reloading compartment for new blades, and a storage compartment to keep additional blades. The blade magazine is loaded from the rear of the knife body and is locked inside. A working blade may be released before reloaded a fresh blade. The working blade can be extended or retracted multiple times via a blade transport mechanism. The blade magazine may be extracted via the lock mechanism and pushed out by a spring designed for this purpose. The blade transport mechanism, the blade release mechanism, and a blade lock mechanism work in cooperation to allow extension and retraction of a blade, disposing of a blade, and reloading of a blade.

A cushion back cutter is formed from a first side plate, a second side plate, and a center plate between the first and second side plates. The center plate includes a slot that forms a blade holding pocket with a bottom opening to receive one or more blades. A blade clamp is inserted into the blade clamp opening of the first side plate, and a blade clamp fastener tightens to cause the blade clamp to press the blades against the second side plate to hold the blades in position. The center side plate forms a row guide for guiding the blades of the cutter between adjacent rows of carpet tufts. The row guide may include a region having continuous notches, which tend to move the carpet tufts out of the path of the blades to avoid shearing them.

Presented embodiments of the handheld cutting tool are capable of cutting in one of two ways: with the cutting edge of the blade only so as to minimize damage to objects not intended to be cut or, alternately, with the point of the blade as with more typical knives. The tool is comprised predominantly of a handle body, a blade holder and a rotational control assembly for allowing the blade holder to rotate. The blade holder holds either a replaceable isosceles trapezoid utility blade or replaceable single edge razor blade and has, in some embodiments, a portion that isolates parts of the blade from objects not intended to be cut. The rotational control assembly enables the blade holder to rotate between retracted and a plurality of extended positions thus permitting the blade holder to deploy the blade at various angles to facilitate proper cutting of materials.

A lightweight, handheld screen trimmer (10, 20, 30, 40) which aids in trimming excess screen (340) and also in removing, tucking in, and trimming spline (320). The screen trimmer (10, 20, 30, 40) assists in several tasks relating to removing, replacing and installing screening (330) in a screen frame (300).

A utility knife constructed of a lower shell (102), an upper shell (104), a retaining knob (106) and a hinge pin (108). The hinge pin (110) provides a high-strength connection between lower shell (102) and upper shell (104). Retaining magnets (110) and (112) retain steel utility blades in place when shells (102) and (104) are separated from one another. According to one embodiment, the retaining magnets (110) and (112) are permanent magnets made of an alloy of neodymium, iron and boron.
