Abstract: A knife holder includes two transparent plates, a plurality of partitioning blocks, a plurality of securing blocks, and a plurality of larger securing blocks. The partitioning blocks are spaced equi-distantly apart between the plates such that the plates define a receiving space. Upper ends of the plates are provided with a plurality of pairs of opposite indentations. The receiving space and the indentations are sized to receive knives. The knives are divided by the partitioning blocks so that they do not overlap. The partitioning blocks have front and rear ends forming bolt portions that pass through corresponding through holes in the plates for screwable engagement with the securing blocks so that the plates can be screwably secured on the partitioning blocks. The larger securing blocks are secured at two lower corners of each plate so that the knife holder can stand on a planar surface.
