Adjustable-tone deer call having a metal slider

An adjustable-tone deer call device comprising:

• a barrel assembly comprising an outside barrel and a small inside barrel, the outside barrel having an inlet end adapted to serve as a mouthpiece, and having an outlet end for air, and the small inside barrel having an open proximal end secured inside the outlet end of said outside barrel and a distal end for air to exit;
• a reed mounted for vibration within said barrel assembly, said reed having a proximal tree end toward the inlet end of said outside barrel, the reed generating a sound of a selected pitch when air passes through the small inside barrel;
• a reed holder supporting the reed at its distal end within said barrel assembly, and having sidewalls and a bottom, together forming along with the reed, an elongated air flow channel;
• and
• a metal slider mounted for longitudinal movement within said outside barrel and atop the small inside barrel, the slider being adapted to clamp the reed at a line of contact to the reed holder at a range of positions selectable by axially sliding the metal slider, thereby confining the length of the vibrating reed to a predetermined dimension and producing sound of a selected pitch;
• wherein the metal slider is a strip of metal having at least the following folds;
• a first fold forming a user-erasable upstanding movable tab, the movable tab extending outside of the outside barrel;
• a second fold at an acute angle forming the beginning of said metal slider;
• and
• a third fold which defines the line of contact with the reed.
