I like the sheath mods, the dangler idea is a nice way to wear the pack and the knife.

I usually carry my knife in the pack instead to prevent loss. If I am going to be using the knife while wearing the pack, I usually rig the sheath for around the neck carry. Only works with a small knife, like a Mora 510 though.

I have a few leather danglers just never gave them much play. I guess I need to try them out with a pack on. Cheers!
