A kitchen knife holder comprising: a holder body for suspending a kitchen knife (h) entirely by holding a top (t) of a spine (bh) of the kitchen knife (h); and a magnet array attached to the holder body, including two or more magnets spaced at an interval and arranged in an array pattern, and configured to be capable of reliably suspending the kitchen knife (h) at the lower surface of the holder body while a cutting edge (b) of the kitchen knife (h) is pointed downward, and said magnet array being used for magnetically supporting the top (t) of the spine (bh) of the kitchen knife (h) in a manner allowing the top (t) to be attached and detached freely; wherein the magnet array is arranged at a substantially center position of the holder body in a width direction as viewed from one end of the holder body; whereby the top t of the spine of the kitchen knife h is magnetically attracted to the magnetic field center of each magnet and to the center of the kitchen knife holder 1 in the width direction; wherein the permanent magnet in a thin part of the holder body magnetically is configured to attract a top of a spine of the kitchen knife reliably to allow the kitchen knife to be suspended reliably with the edge of the kitchen knife pointed downward, characterized in that the holder body 10 is composed of a thick plate-like member extending long in one direction, with respective plate surfaces of said plate-like member arranged at upper and lower positions, the respective centers of the upper and lower plate surfaces are recessed like grooves extending in the lengthwise direction over the entire lengths of said plate-like member to form recesses of the holder body, wherein as a result, a shape like an iron dumbbell is defined as viewed from an end surface in which a part sandwiched between the upper and lower recesses at the centers forms said thin part, and opposite end sides form an enlarged part; whereby a connection between the lower thin part and the lower enlarged part has a wall surface tilted downward in a direction of expanding the connection to form a trapezoidal space ST, whereby the top (t) of the spine of the kitchen knife is magnetically attracted to the center of this space, and sufficient clearance is formed on the opposite sides of the kitchen knife. a magnet array attached to the holder body, including two or more magnets spaced at an interval and arranged in an array pattern, and configured to be capable of reliably suspending the kitchen knife (h) at the lower surface of the holder body while a cutting edge (b) of the kitchen knife (h) is pointed downward, and said magnet array being used for magnetically supporting the top (t) of the spine (bh) of the kitchen knife (h) in a manner allowing the top (t) to be attached and detached freely; wherein the magnet array is arranged at a substantially center position of the holder body in a width direction as viewed from one end of the holder body; whereby the top t of the spine of the kitchen knife h is magnetically attracted to the magnetic field center of each magnet and to the center of the kitchen knife holder 1 in the width direction; wherein the permanent magnet in a thin part of the holder body magnetically is configured to attract a top of a spine of the kitchen knife reliably to allow the kitchen knife to be suspended reliably with the edge of the kitchen knife pointed downward, characterized in that the holder body 10 is composed of a thick plate-like member extending long in one direction, with respective plate surfaces of said plate-like member arranged at upper and lower positions, the respective centers of the upper and lower plate surfaces are recessed like grooves extending in the lengthwise direction over the entire lengths of said plate-like member to form recesses of the holder body, wherein as a result, a shape like an iron dumbbell is defined as viewed from an end surface in which a part sandwiched between the upper and lower recesses at the centers forms said thin part, and opposite end sides form an enlarged part; whereby a connection between the lower thin part and the lower enlarged part has a wall surface tilted downward in a direction of expanding the connection to form a trapezoidal space ST, whereby the top (t) of the spine of the kitchen knife is magnetically attracted to the center of this space, and sufficient clearance is formed on the opposite sides of the kitchen knife.
