Yup, hardness 21+ due to repeated castings of any number of transmutation spells. (I forget which ones raises hardness of metal/wood).
Thought that your adamant shortsword or dagger was a canopener you could hide to get yourself out of anything?? HaHAH! Not anymore. Good luck dealing enough damage to hurt it.

This is why you build your sunder monkeys with Sense Weakness, so you can reduce and then pierce hardnesses up to 24 with your standard adamantine implement of sequence breaking.
