10,000 durability = 10,000 attacks on opponents, so if you use it on every mob you attack, it will run out very quickly and will need the repair kit fast. I only use mine on bosses, so I have been able to stretch mine out. I have had it since October, 10,000 durability, and it has 1200 left on it. I have not repaired it yet. You also get warnings on screen when you get close so you don't forget to repair it. If it goes to zero, it breaks and is gone forever.
