The legendary axe is just stupid. It has a sharpness 1 knockback 2 enchantment and deals 6 damage. The iron sword has sharpness 2 and knockback 1 dealing 8 damage points (4 hearts AND IT COSTS LESS THAN THE IRON SWORD. They should have made the legendary axe a diamond axe with sharpness 3 and knockback 2. It would be more reasonable.
