An apparatus for cutting an item, such as a roast, a bagel, or a loaf of bread, comprising first and second wall devices, a cutting board device, and a base. The first and second wall devices may each have a plurality of vertical slots which are parallel and spaced apart from each other. The first and second wall devices may be configured to be attached to the base in a manner such that the first wall device projects out from the base, at an angle. The cutting board device may include a cutting board body and pins for removably supporting the cutting board device by both the first and second wall devices so that first and second parts of the cutting board device rest on the first and second wall devices to thereby support and suspend the cutting board body above and substantially parallel to the base.

Devices and methods are provided for slicing an item such as a bagel. An apparatus includes an upper assembly with a blade and interior vertical rails, and a lower assembly with a holding plate, movable centering plates, and exterior vertical rails with a slot for an external cutting device. The lower assembly also includes a cam mechanism to activate the centering plates. A method involves depressing actuators to separate the centering plates, creating space for a food item. When the food item is placed on the holding plate, the actuators are released, applying equal force to center the food item. The device also includes a centering device and an actuator that, upon receiving force, engages the centering device to hold the item in a cutting position for the blade. The device cuts the item within about +/one-sixteenth of an inch.

The present invention relates to a bread slicer, comprising: a storage box, comprising a box body, an installing frame and a cutting disk, wherein the box body is provided with an accommodating chamber, the accommodating chamber can accommodate cut bread slices, an upper end of the accommodating chamber has a first opening, the installing frame is installed at the first opening, the installing frame is provided with a second opening opposite to the first opening, and the cutting disk is slidably inserted into the installing frame to open or close the first opening and the second opening; and an auxiliary cutting assembly, detachably installed on the installing frame, wherein the auxiliary cutting assembly can limit a cutting position of a cutter to cut bread slices of a preset thickness. The storage box has the function of storing the bread slices.
