    摘要： AFTER THE SLOTTED FRONT END OF A SLEDGE HANDLE HAS BEEN STARTED IN THE PASSAGE THROUGH A SLEDGE HEAD, THE HEAD IS HELD SATIONARY WHILE THE FRONT END OF THE HANDLE IS PUSHED THROUGH IT AND OUT OF ITS FRONT. THE PROJECTING FRONT END OF THE HANDLE THEN IS REMOVED. THE FRONT END OF THE REMAINDER OF THE HANDLE IS PUSHED AGAINST A STATIONARY BLADE

    TO OPEN THE FRNT END OF THE HANDLE SLOT. THE HANDLE THEM IS MOVED FORWARD AGAINST A STATIONARY WOODEN WEDGE TO FORCE THE EDGE INTO THE SLOT. FINALLY, THE HANDLE IS PUSHED FORWARD AGAINST A STATIONARY METAL WEDGE TO FORCE THE HANDLE ONTO THAT WEDGE ALSO.
