One that actually makes sense. Sorry, but your analogy completely backfires considering uncut diamonds do NOT have the same properties of diamonds in a diamond saw, being the most obvious one that the latter diamons are fabricated by the compression of graphite, which allows them to be tougher than natural diamonds, thus being able to cut them.
And having the same properties does NOT answer the question. How is Senjutsu having the same properties as Nature Chakra a counter? After all, casting a Katon against another Katon doesn't automatically translate to a victory as it does in this case. So, I ask again, why does Senjutsu counter Natura Chakra? Neither you or KYF have answered this question properly.
