The difference between a clove and a munter is their function. The munter is a hitch that increases friction and allows you to belay a climber. The munter is also known as HMS, an abbreviation for the German word Halbmastwurfsicherung which means half clove hitch belay. The munter is critical to know in case you ever drop your ATC or GriGri. The clove is used to secure yourself to a climbing anchor. The munter allows rope to move (with increased friction) and the clove cinches the it tight.
