Japanese wood saws cut the material on the pull stroke. This means that the teeth are angled towards the person using the saw.
If half way along the blade, the teeth started to face forward, then it would cut equally on both the pull and the push stroke.

But it still wouldn't cut any faster. |

[Rayford] Yes, but on the plus side, it would be much
harder to use |

Doesn't make any sense, unless it's a two-man saw. |

//don't you lose that advantage by pushing?// No - the forward facing teeth make an identical cut, but they only make their cut on the push stroke |

Better to have the teeth facing forward on one side and backwards on the other. Then you just take the saw out of the slot at each end of the stroke and flip it. Assuming the removal, flip and re-insertion takes zero time, this will make your saw cut twice as fast. |

Or have each tooth of the saw mounted on a tiny,
motorised pivot. Then when you have pushed the saw
through the wood, each tooth would pivot to face in
the opposite direction, ready for the 'pull' stroke.
This way, you'll be able to cut in both directions. |

I think a one man cross-cut saw fits this description. |
