Sheaths, holsters, what have you. I'll start with a sheath for a mora companion with a loop for horizontal carry.
What a great thread idea! Hers a couple, left is an Azwelke for Izula, on the right is a custom slotted type for a LTC Machete, courtesy of Reagalia Innovations.
This is what I got for my Mora Companion HD, Armory Plastics via Blade HQ. Not perfect but definitely secure and affordable for average folks.
