More like needing to press two buttons--but you can only reach one at a time. If the magic exists in the same place as the physical, you [i]have[/i] to be able to cut the physical to cut the magic. If the enchantment puts the weapon beyond something Guts can cut through sheer force, the weapon's integrity won't be compromised.

Yeah, but in that case it would need to boost the weapon's durability to unbelievable levels. Guts smashed corundum during one fight.
