Claw Durability on a Kicker

[KelKnowles]

I have my kicker built with claw shield and a normal claw right now. My question is, if i only use dragon talon and dragon flight to attack, and am not using claw block, can i use an ethereal claw indefinately or will it break? What about if I change to dual claw, will it take the durability then?

Thanks in advance.
