Follow the instruction below to get duplicated weapons and the trick can only work on certain type weapons, except guns and bombs, and not all the characters can perform the trick such as Logan with mastered Boomerang skill.
1) select weapons that are throwable and retrievable on the ground such as melee, knives.
2) throw a weapon out, and quickly access to "select" before the weapon touch down on the ground, then go to "inventory"
3) unequipped the weapon that you just throw out in step 2
4) go back to the in-game screen, pick up the weapon on the ground
Check your inventory, now you will get two copies of the same weapons.
Equip the weapon you wish to duplicate, then throw it. Quickly enter your inventory screen while the weapon you threw is still in mid-air and unequip it from your character. Exit the inventory menu and pick up the the weapon you threw; it should now be duplicated when you check the inventory screen again.
