why doesn't he pull the saw out?

When it was still live, he suffered from unfortunate love. After some evolutions, it has pulled out to itself(himself) heart and has died. The certain well-wisher who has remained behind a shot has thrust in a body with an unwrapped thorax an old and rusty saw. As it is strange, the given action of Murzikza has reanimated. Since then - if to take out to it a saw from a breast - he dies. If to insert back - revives.
The kind Doctor (тм) has put Murzikza in order and cut off acting parts of a saw, having sewn up thus a thorax. So in drawings of later period - saws it is not visible, but it all the same there.

Now this actually makes sense... no, it doesn't, but I don't know the proper English words... I wouldn't even know how to say it in my mother language, so I'll just say: it makes sense as a story.

'cause he will die.

translations?
