A hand held rotary cutting device having an annular cutting blade with an interior diameter entirely protectively enclosed by a housing, and with a sharpened periphery partially protectively enclosed by the housing, wherein the housing has similarly configured front and rear components that are movable between an open position that permits removal of the cutting blade for cleaning, and a closed position wherein the front and rear components cooperate to rotatably support the cutting blade, and to define an elongate handle that overlies a housed portion of the cutting blade. Cutting pressure, stability and unusually effective guidance are supplied to the cutting blade by novel C-shaped lower portions of the front and rear components of the housing that extend continuously along opposite sides of the cutting blade just above and quite near to where selected portions of a long, exposed C-shaped reach of the sharpened periphery of the cutting blade is available to sever thin food such as pizza.
A hand held rotary cutting device comprising a housing and an annular cutting blade having an internal diameter entirely protectively enclosed by the housing, and having a sharpened periphery that is only partially protectively enclosed by the housing leaving a C-shaped reach of the sharpened periphery exposed for engaging and severing foods, wherein the housing 1) includes front and rear components that are movable between a closed position wherein the housing rotatably supports the cutting blade and an open position that permits removal of the cutting blade for cleaning, and 2) includes a releasable retainer to retain the front and rear components in the closed position, with the front and rear components cooperating, when in the closed position, to provide C-shaped lower portions that extend along opposite sides of the internal diameter of a portion of the cutting blade that defines the C-shaped reach of the sharpened periphery of the cutting blade that is exposed to engage and sever thin foods, the C-shaped reach of the sharpened periphery that is exposed forming a majority of the sharpened periphery.
A rotary cutting device having a housing and an annular cutting blade with an internal diameter that surrounds an open central region of the annular cutting blade and with a sharpened periphery partially protectively enclosed by the housing having similarly configured, pivotally connected, front and rear components movable between open and closed positions that cooperate when in the closed position to rotatably support the cutting blade, to entirely enclose the internal diameter and to define an elongate handle of bulbous shaped cross-section overlying a fully housed angular reach of the cutting blade enabling a portion of a hand to reach through the open central region while grasping the elongate handle, and wherein a latch is adapted to releasable retain the front and rear components in the closed position.
A hand held rotary cutting device having an annular cutting blade that protectively overlies a full length of an internal diameter of the annular cutting blade having an open central region defined by the internal diameter and having a sharpened periphery that is protectively shielded along at least about a 150 degree reach of the cutting blade by front and rear portions of the housing that are pivotally connected to move between an open position that permits the annular cutting blade to be removed for cleaning, and a closed position wherein the front and rear portions of the housing cooperate to define an elongate handle of bulbous shaped cross-section that overlies a majority of the shielded reach of the sharpened periphery of the cutting blade that is able to be grasped by a portion of a hand extending through the open central region, with one of the front and rear portions carrying a latch adapted to releasable retain the front and rear portions of the housing in the closed position.
A hand held rotary cutting device comprising an annular shaped cutting blade and a housing having substantially identically shaped, pivotally connected, front and rear components each having C-shaped lower portions and being movable between an open position that permits removal from the housing of the annular shaped cutting blade, and a closed position wherein the front and rear components cooperate 1) to rotatably support the annular shaped cutting blade, 2) to protectively shield an entire portion of the annular cutting blade that extends along an internal diameter of the cutting blade via the C-shaped lower portions, and 3) to protectively shield at least about a 150 degree reach of a sharpened periphery of the annular cutting blade leaving an exposed C-shaped reach of at least about 200 degrees of the sharpened periphery of the annular cutting blade for engaging and severing food.
