Because of the way that factorio's weapon system works, I also need the "ammo" for the swords. For the two low level swords, I need a graphic that represents a whetstone. For the two upper level swords, I need a futuristic-looking battery, to hold the charge that will be given to the energy swords.
Thanks in advance for any help!
EDIT: For more info, the sprites are intended to go into the weapon slots, so however big those slots is how big that the sprite has to be. Reference 'Pictures':
