More and more often I see the Sam Browne stud used as restraint to keep a sheath from sliding down from a within the waistband carry. This was not the original intention of this or any other type of stud. The stud was originally used as a secure fastening device for a detachable belt loop known as a "FROG" and often seen in the carry system of military bayonets and, on occasion, swords. The Sam Browne stud, considering its small size, is not a good choice for carrying a knife on your person in an inside the waist band carry. A stud with a much larger diameter head can be used but still has the disadvantage of a tight sheath being withdrawn from the inside the waist band carry along with the knife---bummer! If you do not have the facility or ability to create large diameter studs you can substitute good quality door or drawer pulls and rework them by shortening the post portion to accept, closely, the thickness of the belt used. The SB stud works quite satisfactorily with a frog but has doubtful benefits without the frog---------------Sandy
