Method for severing the ends of tubing by feeding the end of a tube through a die such that its end to be sheared extends beyond the die while presenting a shear blade with a pointed end in the interior of the tube end. After the shear blade is inserted into the tube, relative vertical movement between the shear blade and the tube is effected to cause the pointed end to initially puncture the tube wall adjacent the die. The shearing blade is thereafter shifted laterally and vertically to shear remaining portions of the tube wall.
