Have you ever felt inconvenienced by having to carry both a shotgun scabbard and a machete sheath during a zombie invasion? If so, Voodoo Tactical has a solution for you – the Shotgun Scabbard With Attached Machete Sheath. I am not kidding. This is real and, if I am completely honest, kind of cool. 
This is the first and probably the last time that you will see Voodoo Tactical on these pages.
FWIW, I have a Voodo Tactical double rifle case and I’ve been very pleased with it. I’m not planning to take it into “action,” but it is a good tool for range trips.
You’d need arms like an orangutan to reach over your shoulder and draw the gun. The same applies to swords. It’s just quicker and easier to use a sling. Duh! Sheaths like this only add weight and bulk.
