This is the matching sword sheath for the Mytholon HK elven long sword. It fits very well with the "Doran" back system and can be worn on a belt, just as well as on your back. The sheath is opened on the bottom, so the blade can be seen.
This sheath can be worn on your left side, as well as on the right one.
The short variant at 38cm long is suitable for a long dagger or dirk.
