This Armatus Carry Architect sheath for the Bradford Guardian 3SF G10 Sheepfoot is a top-quality kydex sheath with many mounting options. It is a tight fit so you can be sure that the knife stays in place. Even when you're running. And yet you can also easily remove it from the sheath by placing your thumb against the raised lip on the top of the sheath when taking it out. This tells you that Armatus knows really well what they are doing when it comes to kydex.
