So basically, the chi chakra chemically combines with the chakra metal during the forging process. Like how two elements in real life combine to form a new compound with properties distinct from the original reactants, chi chakra and chakra metal combine to form a new substance, so technically the chi chakra is no longer chakra. Yumi's bio chakra cannot destroy the chi chakra without destroying the metal, due to the fact that the two are chemically combined, and since chakra metal cannot be damaged by any form of chakra, Yumi's bio chakra should not be able to damage the Tenshiken.

There are two kinds of chi chakra involved in a murakami sword. The first kind is the one involved in the forging. As I explained above, that should not be affected by Yumi's bio chakra. The second kind is the chakra that the wielder channels into it via chakra flow, making take on a red glow and appear to be on fire. That chi chakra is not combined with the molecular structure of the chakra metal, so Yumi's bio chakra can destroy that.

The Tenshiken fails to penetrate the Lightning Release Armor in Miyuki's first attempt because the Chi Chakra that granted it extreme cutting power was eaten by the bio chakra. The Tenshiken didn't have enough energy to pierce the armor hence it was deflected. However, when Yumi is about to kick Miyuki, she is moving very fast, and thus the force she exerts on the sword would be very great. The point of the sword has a very small area, and thus the pressure that is on the Lightning Release Armor is very large. That allows the Tenshiken to go right through the Lightning Release Armor, and continue on to Yumi.

Sorry if this is long, but I wanted to show you why I think the stabbing would work. If you disagree tell me and I'll change it :D
