I'm curious - I use an assisted opener for my EDC, but sometimes getting it off my belt is more time consuming than it should be. For lift and tall ladder work I wear a neck knife. I've acquired several with 5.11 boot purchases and the "boot knife" can be rigged for a "neck knife". If I'm rigging, or just cutting old rigging away and hanging on with one hand I like the idea of going for the chest as opposed to the belt.
Anyone else wear one for job specific or just a convenience or even a cool factor?
Believe me I'd like to get a fitted kydex sheath made for one of my Del parers - I think they'd make excellent neck knives.
