Abstract: A tool handle permits selective adjustment of a permitted depth of insertion of a blade therein. The tool handle includes a central bore for reception of a blade through a front opening thereof, and an adjustable stop receivable in the bore, the position of which can be selectively fixed along a longitudinal central axis of the tool handle. So positioned, the stop blocks insertion of the blade beyond a fixed point along the bore selected by the user. As the blade is worn and reground, the stop is moved to a position closer to the front opening of the bore, shortening the degree of blade insertion permitted, and thus allowing a constant distance of blade extension to be maintained. Once adjusted, the blade is securable to the handle, to prevent undesirable movement during use of the assembled tool.

Abstract: A knife and a reversible blade are described. A handle provides a blade mount for an elongated blade having opposed longitudinally overlapping first and second cutting edges.

The utility knife has a safety lock which is able to enhance the assembly between the body halves, such that even when the release mechanism of the knife is accidentally operated or the knife accidentally falls to the ground, the knife body halves are still securely attached with each other.

Abstract: A blade holder attached to a saw handle. The saw blade includes a slot on one side, and is engaged inside the blade holder and is securely held in place by stoppers formed inside the holder's frame and by pressure applied by spring action. This spring action is created via a turning of a knob and attached pressing part and protrusion. When the knob is in a loosened position, the blade is easily removed and replaced through a holder receiving part. A new blade is received through the receiving part and by tightening the knob, the new blade is thereby secured in the holder.

The two casings are pivotedly joined at one end thereof . The first casing has an insert mounted therein. The insert defines a slot thereon. The second casing has a fitting member extending from an inner face thereof and through the slot of the insert. By urging the insert, the fitting member will be interlocked with the periphery of the slot so that the first casing is engaged with the second casing. By releasing the insert, the first casing and the second casing will open to facilitate a disposition of the blade, without separating the pivoted joint thereof.

Abstract: A hand-held utility knife (20) has two handle portions (22, 23) hinged together at the rear end (26) of the handle (21) by means of two lugs (36, 37) of one handle portion (22) projecting into two recesses or cavities (38, 39) of the other handle portion (23) and retained therein behind two lips (53a, 53b) except when almost closed together, when the two handle portions (22, 23) can be separated and reconnected. In order to prevent inadvertent separation of the two handle portions (22, 23) at their rear ends (24, 25) when the handle is closed and the clamping device (27) is screwed up tight, the lugs (36, 37) have abutment portions (61, 62) which engage abutments (65, 66) inside the two recesses or cavities (38, 39). The abutments (61, 62, 65, 66) are positioned on one side of the hinging axis (34) so that they move apart when the handle (21) is opened. Hence the abutments (61, 62, 65, 66) do not interfere with the hinging of the handle portions (22, 23) nor with their separation and reconnection.

Abstract: A floor covering cutter for cutting floor coverings such as carpets, has a shell handle (3) consisting of several parts and a cutting blade (6) that is gripped with its cutting head at an angle of deployment with respect to the longitudinal axis of the shell handle between the shell parts of the handle that are connected with a screw. They enclose a storage area (12) for spare blades on the inside and present a gripping contour on the outside. The cutting blade is positioned with its cutting head at a slight forward angle of deployment with respect to the theoretical mid longitudinal axis (7) of the handle shell, while the handle shell, on the end opposite from the cutting blade (6), presents a steadily expanding outer cross-section (4) with flattened contours in the area adjoining the gripping surface (3). In the storage area (12) are kept blades standing on one edge. The two shell parts (1,2) are connected by a joint and held together by a knurled screw (10).

Abstract: An improved tool head for releasably retaining a blade includes a body and a clamping member pivotally hinged together for relative movement therebetween by rotation of a threaded operating member. The operating member is rotatable to axially move the same into threaded engagement with the body and clamping member and, at a final point in its axial translation, contacts a camming structure on the clamping member. Engagement of the operating member with the camming structure applies a laterally directed force to the clamping member, pivoting the same about its hinged connection to the body and carrying a pair of blade receiving lips on the body and clamping member into relative blade-retaining proximity to firmly secure a blade between the lips.

Abstract: A knife comprises a tension rod insertable into an opening extending through a handle, and a bolt at one end of the handle and in threaded engagement with the tension rod for retaining a replaceable blade at the other end of the handle. The tension rod comprises two elongate parallel rod portions of rigid material, one of which is provided with pins engageable with holes in the blade for retaining the blade between adjacent ends of the rod portions.
