ABSTRACT:
A brick cutter includes a base, a swing arm that has a handle portion, wherein the handle portion has one end pivotally connected to the base and an opposite end formed with a head so that the swing arm is capable of swinging relative to the base, and a chisel that has a cutting portion and a rod portion, wherein the rod portion is coupled with the head of the swing arm. Thereby, when a user holds the swing arm with one hand, and hammers the chisel with a hamper held in the other hand, the hammered chisel impacts a brick so as to cut the brick.
