A lathe tool holder for holding a lathe tool, tool holder and tool constituting an elongated lathe tool assembly in which the tool extends forwardly from the tool holder, the assembly being adapted for hand-held use by a turner for engagement of the tool with a surface of a rotating workpiece, the surface moving downwards relative to the tool assembly and the tool assembly being at least partially supported by a generally horizontally extending tool rest for operation in a generally horizontal plane of use, the tool holder comprising:

  • a forward tool receiving portion having a longitudinal axis approximately defining an axis of rotational adjustment;

    a butt portion extending rearwardly from the tool receiving portion for holding by a turner to at least partially control the tool;

    a handle included in the butt portion and extending obliquely from the tool receiving portion, the handle having a longitudinal axis and said axis diverging from the axis of rotational adjustment including a receptacle for receiving a tool and means for releasably holding the tool in the receptacle and operable to apply a torque about said axis, the tool assembly being adapted to receive the support of the tool rest at a forward portion of the assembly, said rest having a tool supporting surface defining approximately the generally horizontal plane of use;

    an elongated rearward extension of the butt portion extending from the handle and approximately parallel to and offset from the tool receiving portion;

    upwardly open cradle means carried by the rearward extension of the butt portion, engageable with a forearm of the turner for assisting the turner to control the tool in operation; and
