I have two Guardians, and the size of the knives is pretty close to Fällkniven's G1 Garm Fighter, both being black coated.
The sheath for the Guardian lets you adjust the tension required to release the knife, and it has a moveable clip, which allows for upside-down carry. The sheath is noisy though, and if I'd have to choose between G1 and the Guardian, the G1 would win.
It has a neck kydex sheath, but Fällkniven has just released a belt loop device for the sheath. The G1 has VG-10 steel. I love my G1.
