Benchmade Rescue Hooks have done nothing but impress me. My favorite is the 7 Hook and I am always on the lookout for a better way to carry them. I think I may have found it at Vigilance Tactical.
VigiTac makes a slim, low profile sheath for the 7 Hook that is barely more than a cover. It has two small wings that allow it to lock into place in a single column of PALS webbing. This looks perfect for use on the side of a IFAK pouch like the HSGI Bleeder/Blowout Pouch. It could probably even be tucked in behind other pouches.
