In regards to my previous entry on "arrow catching", I'm posting pictures of several different arrow types, to give non-archers some notion of what it is we're talking about on the Mythbusters forum:

First, typical "target" arrows as used in sporting competitions:



Note the small, aerodynamic fletching. These arrows are made for consistency.

Second, a "flu-flu" fletched arrow:



This is just one style; using un-trimmed feathers. There are others, including using a feather wound spirally around the shaft, and using a larger-than-normal number of regular feathers (as many as six).

Finally, Japanese feudal-era arrows used by Samurai in warfare:



Note that these are actually fairly contemporary arrows used in the practice of Kyudo (a meditational form) I found actual photos of period Samurai arrows hard to find!
Still, from book illustrations, the arrows with the long, thin fletchings in this period are pretty close.
These arrows would have been fitted with razor-sharp forged arrowheads in a variety of styles.
