Both extractors are used to remove either the hammer head of butt for the hammer shank. The screw type mechanism exerts even pressure to prevent damage.
The beveled plate with adjusting nut is used on hammer heads set at an angle.
The regular upright extractor can be used on all shanks measuring greater than 3-1/4" long, wheras the spinet extractor can accommodate a shank distance only 2-3/4" long.
Both tools are nickel plated.
