By coincidence I found a website of Lone Wolf Archery. The bowyer John Maus builds a longbow called Autumn Storm that features limbs with a concave cross section. I could not find anything about this bow and this always makes me curious   :eek:
Has anyone of you ever heard of this bow or even shot one? Any info and pics are appreciated.
Thanks,
Joe

I own one.  The limbs are completely conventional (parallel back and belly) except the fiberglass on the back is sanded on each edge of the limb.  The only non-conventional shape on the limb is attributable to the edges of the glass on the back being sanded, yielding a slight convex shape to the back.  There isn't a concave surface anywhere on limb, much less a concave cross section.

John, many thanks for your informative answer. How does the bow shoot?

It's a very nice bow. Beautiful craftsmanship and shoots great.

John, I read a few things about these bows as well...

Thanks for your answer, I thought it was very informative and classy as well.
