Claim:
A hand tool comprising a hammering body, a handle, and a vibration-damping sleeve, wherein the hammering body is provided with a through hole; the handle is a long rod; the vibration-damping sleeve is a hollow tube substantially in the form of an awl, one end of which is sealed and the other end is open, in which the diameter of the sealed end is larger than that of the open end and an exterior wall near the sealed end is provided with an upper cave, a lower cave opposite to the upper cave, and two convex sides opposite to each other; a first end of the handle is inserted into the vibration-damping sleeve through the open end of the vibration-damping sleeve; and a second end of the handle opposite to the first end is made to pass through the through hole of the hammering body so that the two convex sides of the vibration-damping sleeve are tightly connected with the hammering body and the upper and the lower caves are positioned respectively at two inner walls of the through hole to buffer the hand tool from vibrating.
