Abstract: A pocket sized weed grinder is provided herein. The weed grinder includes a single board, including at least four panels, at least one folding line disposed between adjacent panels of the at least four panels, for forming a closed flat cell between two of the adjacent panels, and two grinding plates, each grinding plate disposed on each of two of the adjacent panels. At least one of the two grinding plates is movable in linear motion with respect to the other. The weed grinder enables grinding of weed, accumulating the ground weed within the weed grinder and pouring the ground weed to a smoking paper, while avoiding the need of a mediator element to which ground weed is poured and from which ground weed is poured into a smoking paper, as in currently used weed grinders.
