A food cutting device with a handle adapted to be held in a user's hand and a detachable cutting wheel for cutting a food item, the detachable cutting wheel has a circular blade and an axle projecting therefrom, the handle has a retaining pincer adapted to grasp the axle, allowing the detachable cutting wheel to freely rotate therein, and has a pincer gap which allows the axle to be alternatively inserted or removed. The axle has a retaining flange positioned parallel to the circular blade, preventing lateral shifting of the detachable cutting wheel by abutment between the circular blade, the retaining flange, and the retaining pincer positioned therebetween. The handle further has an upper blade guard and a lower blade guard adapted to protect the user's hand from the circular blade.

A rotary knife includes a frame, an annular blade, and a blade housing mounted to the frame. The housing presents a circumferential mounting surface in contact with the frame. The housing supports the blade on the frame for rotation about a central axis. The housing includes a blade-supporting race defined along a circle centered on the central axis. The mounting surface is defined along a circular arc with a center point spaced from the central axis, such that the blade-supporting race and mounting surface are eccentric relative to one another. The housing presents opposite inner and outer annular faces. At least one of the faces presents a proximal-most end in contact with the frame and a distal-most end spaced from the frame. The proximal-most end is spaced from the central axis a first distance. The distal-most end is spaced from the central axis a second distance. The distances are different.

A quilt binding cutting guide and a method for using it to cut and form low-bulk, angled seams for quilt bindings. The quilt binding generally has a first end and a second end. The cutting guide may comprise a quilt edge line, a right binding cutline, and a left binding cutline, the right binding cutline and the left binding cutline being spaced apart from, and parallel to, each other, and angled with respect to the quilt edge line. To use the guide, a user may position the cutting guide on top of a quilt so that the quilt edge line is directly above a raw edge of the quilt. The user may then use the guide lines on the cutting guide to position and cut the ends of a quilt binding accurately, without measuring or marking.

A cutting device includes cutting device includes a housing including an aperture, and a blade cartridge removably coupled to the housing through the aperture. The blade cartridge is configured to hold a plurality of blades. The cutting device further includes a cartridge ejector configured to eject the blade cartridge from the housing.

A power operated rotary knife assembly including a power operated rotary knife having an annular rotary knife blade, a trim guide, and a drive mechanism for driving the rotary knife blade about an axis of rotation. The assembly also includes a portable power unit, a vacuum assembly and a flexible shaft drive transmission coupled between the power operated rotary knife and the portable power unit. The portable power unit includes a drive motor assembly providing a rotational power source which is operatively coupled to the drive mechanism through the flexible drive transmission to rotate the rotary knife blade. The portable power unit also includes a blower assembly providing vacuum pressure at an inlet duct side, the vacuum assembly being in fluid communication with the inlet duct side to generate a vacuum pressure condition in a region of a cutting opening defined by the rotary knife blade and the trim guide.

A surgical rod scorer is provided. The surgical rod scorer includes a pair of elongated shaft members that are pivotably coupled to one another and movable from a spaced-apart configuration to an approximated configuration. Each of the shaft members includes a handle member that is configured for gripping by a user and jaw member that is configured to support respective first and second cutting assemblies thereon. The first and second cutting assemblies each include one or more cutting elements thereon configured and dimensioned to score surgical rod when the jaw members are in the approximated configuration and rotated about the surgical rod.
