I haven't personally come across any of the tools being enchanted. Need to be careful. The lighting on the minecraft objects are a little weird. They'll look like they're enchanted at a glance, but when you use them, they'll just be normal.

not sure if its just for the enchanted axe but usually enemies go flying when you hit them with enchanted axe, not sure about the sword. and i think the crossbow is just like a shotgun not sure how good it is

it says enchanted also it spawned from one of the chests

i think they just do more damage
