Agreed on that Reeves knot, or hangmans noose. Having a fob on my fixed blades aids in a rapid deployment, if required, does give you a little extra length or width, and a bit of string or cord, if you should need it. Knives with bails or rings get some string or cord with some type of pocket hanger. Keeps them more accessible and not inthe bottom of my pocket. Full sized lanyards aren't as necessary here in the Great American Desert, unless you ride a lot. Horses, bikes, or motorcycles. They can be real handy, the long version, for keeping your knife handy, but not in hand if you are on a ladder. That I've done with knives, hammers, etc. to save myself going down a two or three story ladder or scaffold. Co-workers appreciate not having a hammer dropped on them, or knife heaven forbid, from that height as well. YMMV
Thanks, Neal
