While searching for how to change the sheath position I realized that no one ever answered how to change the position of weapons that don't have durability.
So I tried to find out how to do it myself and found a way to change sheath position for all weapons without having to look up their durabilty.
I am not sure if this is the same with all Hex editors but with the one I use I have found that if you select the space just before the next item starts, and go up until the sel reads "-0x68 bytes" that is the sheath position. Items that have no durability will simply read 00.
For this example I've changed the position of the "Flametongue Seal" from hidden to my hip.
Just a reminder
01 - 2H melee weapons (axes, swords, polearms)
02 - Staves
03 - 1H side-hanging weapons
04 - Shields
05 - Guns- It comes out from the back hidden
06 - I am thinking this one is bows or crossbows
07 - Hidden (fist weapons)
