Abstract: A replaceable blade knife comprises two elongate handle portions and a blade carrier assembled together; the blade protruding, or being arranged to protrude, from a front end of the handle, between respective front ends of the two handle portions. The upper handle portion has a thumb-nail-sized aperture through a rear end part thereof. When the knife is assembled, the two handle portions are slid relatively longitudinally of one another, the upper handle portion moving forwardly of the lower handle portion, until a latch part near the rear end of the lower handle portion clicks into latching engagement with the front edge of the aperture in the upper handle portion. The upper handle portion is formed near its front end with two downwardly projecting flank portions, each flank portion having an integral, forewardly projecting piece at the bottom of the flank portion.

Abstract: A holder for an interchangeable knife blade comprising a handle, a chuck adapted to be threaded into the handle. The chuck has a bifurcated forward end defining a lengthwise slot for receiving a flat cutting blade, the bifurcated end defining a cam surface tapering outwardly toward the forward end to a major dimension. A tubular elastomeric ferrule is mounted on the chuck for longitudinal sliding movement relative to the chuck. The ferrule extends between the handle and the cam surface when the chuck is partially threaded into the bore, so that additional threading of the chuck into the bore causes the ferrule to slide forwardly over the cam surface. In this way, the forward end of the ferrule is stretched, thereby transmitting a clamping pressure against a blade which is located in the slot.

These ends of the rod portions are formed with at least one wedge surface for co-operation with a corresponding wedge surface on the handle. This knife construction facilitates cleaning, requires few parts and enables the blade and the tension rod to be readily withdrawn from the handle.

Abstract: The invention is a handle to which a razor blade fastens to form an improved cutting device. The handle includes a pair of rectangular sidewalls being substantially the same size as the size of the razor blade and which have a top edge, a bottom edge, a front edge and a back edge and which are joined together along their respective front, top, and bottom edges to form a casing in which the razor blade is inserted. A corner portion of each sidewall is removed in order to expose a portion of the cutting surface of a razor blade inserted therein. Also attached to the back edge of each sidewall is a tab by which a person can hold the casing between his thumb and his second finger. Attached to the top edges of the two sidewalls is an elliptical plate which is adapted to accommodate the first finger of the person guiding the cutting device thereby.

Abstract: Knives including a cutting blade and one or more wider non-cutting runners projecting slightly beyond the cutting edge of the blade and preferably at both ends of the knife blade. The runners prevent scratching of a substrate on which the material, normally a comestible, is being cut. On each runner there is provided on either side a beveled ramp inclined toward the adjacent cutting surface which acts very much as a plowshare to push up the material being cut against the cutting blade. This prevents a thin strip of material which would otherwise not reach the cutting blade and is particularly important with comestibles such as meat, which are sufficiently tough to permit forming such a thin strip. Where knives are manufactured, the ramps or plowshares can be incorporated in the knife blade when it is manufactured. However, there is included the provision of attachable runners for knives which have already been made.

Abstract: A razor is disclosed characterized by ready interchangeability and safe stability of the blade, a proper protection of the blade during shaving and at inoperative periods, as well as a more "anatomic" handle. A longitudinally extending sheath is connected to a blade handle. The sheath is formed of a single piece of resilient material forming a pair of longitudinally extending wall portions, and a blade holder is disposed between the wall portions of the sheath. A first longitudinally extending section of the sheath is formed with wall portions which converge toward their distal longitudinal edges.

Abstract: A knife having an easily removable blade has an elongated tubular housing having front and rear ends. An elongated stem is proportioned to fit slidably in the housing, the stem widening circumferentially in tapered fashion at the front end of the housing to define a blade-holding chuck having a blade-holding slot. The chuck is circumferentially proportioned to be compressed within the housing when the stem is slid rearwardly so as to contract the width of the slot to a blade-grasping width. A toggle lever is pivotally mounted on the stem at the rear end of the housing, the lever having a beveled edge opposing the rear edge of the housing and adapted, when the toggle lever is pivotally urged to a position essentially colinear with the housing, to contact said rear edge and forcibly slide the stem rearwardly in the housing so as to contract the blade-receiving slot.
