The harp is a lie.

[Ferth]

I will admit that it doesn't need to be 100% physically accurate. I just don't think they should be trying to create a bow that transforms when the outcome is so bad... and the clear alternative is to just carry a harp and a bow.

It's like the joke about Astronauts and Cosmonauts.

When NASA started conducting experiments in Null gravity they came across a problem with ball point and fountain pens not working because there was nothing to draw the ink out and on to the surface of whatever you were writing on, so NASA designed a pen that could write in null gravity, upside down, under water and costs thousands of dollars.

When confronted with the same problem, the Russian Cosmonauts all started using pencils.
