"Horse Bow" is a brand name, not a type of bow. Those bows are made by the
master horse archer and teacher Kassai Lajos. They are fiberglass bows made
in the shape of period styles and worth the money. (I own two) There are
others who make Asian style bows, and you'll notice that the other two
mentioned in the same price range are also made of fiberglass. BTW - I have
seen one of the Korean bows in action, it was sweet.
If you are concerned with period bows made of horn and sinew from Asia like
the ones used by Mongolians, then you should discuss Composite Bows.
Depending on source, The prices range from $850 (the ones I import from
Mongolia) to the $2000-$3000 you will pay for the masterpieces of the likes
of Jaap of Yumi Bows. (I don't own one... yet) You will be hard pressed to
find one cheaper as to properly make one of these it takes at least 1 to 2
I can see how this would price most people out of a period bow competition,
but we already allow period-like bows of modern materials in all SCA
archery, so a period bow only sub category is pointless if you allow
PS - The Japanese "Yumi" bow is an asymmetrical longbow that is not of horn
and sinew construction. Not sure how it got lumped into this discussion
other than that it is sometimes used on horseback, but then so has any other
type of bow for that matter. An asymmetric bow only sub category, now that
would be interesting. It may be Huns vs Japanese only though...
