摘要： The utility knife blade is a blade for a utility knife having a slot formed in the blade that is especially useful when scoring drywall. The slot may engage a tape measure adjacent the tape hook so that the cutting edge at the scoring tip of the blade extends below the tape measure hook to engage the sheet of drywall. The slot extends through the cutting edge into the body of the blade at a slight angle relative to normal, preferably about 10°. The blade has a slot at each end so that the blade may be reversed when one end is dulled or broken. The blade has an otherwise standard configuration, typically having a trapezoidal body with a cutting edge extending along the longer parallel edge and a pair of notches in the shorter parallel edge for engaging knife holder retainer pins in the slidable utility knife holder carriage.

摘要： Cutting members for razors are provided that have been subjected to a localized heat-treating process, e.g., application of laser energy. In some cases, the cutting members include a bent portion, and the localized heat-treating process is used to enhance ductility and thereby facilitate formation of the bent portion.

摘要： A razor blade is provided, which achieves improved safety in use and reduced cutting resistance to an object to be cut such as beard and hair, as compared with conventional razor blades. This razor blade can be obtained by using, as a silicon thin sheet, a single crystal silicon material such as Si wafer or a polycrystalline silicon material including relatively large silicon crystal grains, forming at least one opening in the silicon thin sheet by chemical etching, and forming a cutting edge made of silicon single crystal by ion beam etching without machining such that the cutting edge projects into the opening and has a nose radius of 0.5 μm or less, and preferably 0.1 μm or less.

摘要： In-line razor-blade shaving devices feature two sets of razor blade strips pointing outwardly in opposite directions. The devices are designed for safely and rapidly shaving hair from large body portions such as legs and arms. Each device features an elongated handle arranged in line with an elongated bi-directional razor blade head. Each set of razor blade strips in the head may be provided with one or more straight razor-sharp edges, which point in the same direction, while the blade edges of the two sets point outwardly away from one another, generally in opposite directions. The edges of blade strips of the two sets may be arranged in one common working plane, or each set may be in its own working plane, with the planes at an angle to one another. The working planes are defined by the elongated front and rear guard surfaces of the blade-edge guarding system on the face of the razor head. These guard surfaces contact a user's skin before and after the razor-sharp edges to help ensure safe shaving. The bi-directional head may be constructed in a variety of ways, including in a molded form, in an assembled form, as a replaceable bi-directional cartridge, and as two separate uni-directional razor blade heads arranged in close proximity to one another. These in-line bi-directional razor blade shaving devices represent a new family of wet shaving razor devices. They each can be used with a minimum of effort by sliding the razor blade head back and forth along the skin to be shaved, with shaving occurring in both directions. Some embodiments have two distinct working planes on the head of the shaving device. To use them, the user's wrist rotates at the end of each stroke (or at the beginning of the next stroke), to bring the other working plane, not currently on the skin, into engagement with the skin for the next stroke in the opposite direction.

摘要： The various embodiments of the invention are directed to safety razor heads (1) having an intrinsically fenced unitary blade (7) oriented at a high slicing angle to the shaving direction. The unitary blade comprises a plurality of short blade edges (22) in a spaced relationship across the width of the blade, bounded by leading (19) and trailing guards (8), and oriented at an angle greater than 30 degrees, resulting in enhanced cutting action, improved lubricant and debris flow, and longer life. A method of assembling the cutting edges into unitary form is provided.

摘要： Razor blades for use in shavers and especially in cartridge type razor blade units. Opposite the cutting edge of an essentially rectangular blade, and integral with this blade, there are provided one or more springy, resilient protrusions, in the plane of the blade. During shaving, these enable the blade, due to pressure exerted on the blade, to move a small distance towards the rear of the housing, thus increasing shaving comfort.

摘要： A twin-blade assembly is formed from two blade steel members (A, B) shaped to have rear mounting legs (3A/B), spring arms (9A, 9B) at opposite ends of the unit, downturned legs (2A, 2B) for reinforcing the members and sharpened blade edges (1A, 1B) on blade strips or margins (5A, 5B). The spring arms can flex to permit relative displacement of the strips (5A, 5B). The assembly may also incorporate a lubricating strip (M), the whole unit and strip being discardable and replaceable as a unit.
