I recall something like this previously and haven't seen anything being posted... So here we go, wether it new suggestions or old ones to refresh our thoughts, I think it would be great to opinion them here. I'll start!
More equiptable items for a better quality of life, key rings, tobacco case, hip flasks for beer or wine, maybe even a tool box you could carry in your hand.
Branding, want simply admire your own work? Or are you setting up your own market empire? Either way, this can be a great feature where you could add a signature and or a description, this could also be a great way to keep track of the quality of the item.
Go!
