first i tie one up like this:
and then i loop it through its self like this:
this way i can take on or off instantly whenever i need to like when going through thick brush or when skinning a critter so as not to get it all bloody.what i just showed you is what i consider a lanyard,not these braided things that look pretty at the end.i can see their use in a small knife for an extended grip but i dont consider that a lanyard.it has a name but i forgot it
i bow hunt and i am always using saws and knives to cut limbs while i'm up in the tree.getting up and down a tree with a climbing tree stand isnt fun,easy or quiet so it really sucks when i drop something i need.thats why everything has a lanyard.
i have also had machetes and hatchets and stuff come flying stait out of my hand after hours of chopping.one time my machete flew into a rat infested 6ft deep mini river.it can hit you also if your hand slips after it gets tired.
one more reason is for stabbing downwards.i tie and size all my lanyards in a way to prevent my hand from sliding off the handle and down on to the blade if i had to stab into something hard.if you've ever seen the cold steel videos where they are stabbing their crap through car hoods thay do the same thing.it looks like this.
