Hand tool handle with rotary cap, including: a handle having a seat section at rear end; a rotary cap having a cavity and rotatably disposed on the seat section with the seat section accommodated in the cavity; and at least one projection having a cross-sectional area smaller than that of the rotary cap or the rear end of the handle. The projection is positioned between top wall of the cavity and an end face of the seat section. The top wall of the cavity via the projection contacts with the end face of the seat section. When the rotary cap rotates on the handle, the projection serves as a support point for the rotary cap so as to facilitate rotation of the rotary cap.
