Super strap button

A strap button comprising:

• an inner flange having a contact surface configured to directly or indirectly contact the instrument;
• a lug extending from the inner flange in a direction opposite the contact surface of the inner flange, the lug defining an axis of the strap button along the direction opposite the contact surface with the inner flange toward a proximal end of the axis of the strap button, the lug having a lug width defined by a largest width of the lug in the direction perpendicular to the axis of the strap button, the inner flange having an inner flange width defined by a largest width of the inner flange in the direction perpendicular to the axis of the strap button;
• an outer flange toward a distal end of the axis of the strap button, the outer flange having an outer flange width defined by a largest width of the outer flange in a direction perpendicular to the axis of the strap button;
• and
• a retaining flange adjacent the outer flange along the axis of the strap button toward the inner flange, the retaining flange having a retaining flange width defined by a largest width of the retaining flange in a direction perpendicular to the axis of the strap button,
• wherein the lug width is smaller than the inner flange width, the retaining flange width, and the outer flange width,
• wherein the retaining flange width is 18%-50% of the outer flange width and the inner flange width is 18%-50% of the outer flange width, and
• wherein the lug is configured to support a hole of a supporting strap between the outer flange and the instrument.
