Far more general and crsftable mods since melee weapons are so much easier to lose, these could be cragted or bought, modifications could vary from Grip Tape to increase their durability to stuff like Guard Handle that makes so you have a chance to block and also take no damage while blocking, other posible stronger but more expensive modifiers could be stuff such as a "Tazerwire" makimg your weapon have a chance to inflict shock...
Alternatively there could also be weapon upgrades such as spiked bats and such, reinforching crowbars, sharpening swords and so on
