HMS
מה זה HMS?
HMS or HMS biner are synonims for a pear shaped biner. The origin of the name is the German name for a Munter hitch, Which literally translates to "Half Colve hitch belay". In French too, a munter hitch is called "Half Clove hitch" (demi-cabestan). Back to German. In German Munter hitch belay is called - HalbMastwurfSicherung. Breaking it up, and with a litlle imagination, we get:
Halb - as half,
Mastwurf - mast and wrap, so wrapped around a pole, as a clove hitch,
and finally,
Sicherung - which is similar to securing, or simply, belay.
Put all these back together and we get - HalbMastwurfSicherung - HMS.
A Munter hitch is a hitch tied around a pole or biner, and can serve as an improvised belay device. When reversing the rope direction the Munter hitch plips inside the biner and that requires a wide, pear shaped and symetrical biner. With a D shaped biner, the hitch can easilt get stuck and not flip . So, to summarize, an HMS is a biner that is pefect for HMS belay, or simply, a pear shaped biner.
