Here's my completely novice theory.  It looks like there is a knot in the osage just to the handle side of the break.  Knots cause a stiff spot.  And, this knot is just at the taper of the handle fade where the bow should be bending slightly.  So you handle= stiff area, then you have knot = stiff area, followed by a node= weak spot.  The node area was absorbing on the preasure in transition from handle to limb.  Like I said this is a novice theory.  I've never attempted a lam bow.

My opinion, bad bamboo, shouldn't have broken like that. There is some good and some bad bamboo out there, I have had a bunch of the latter.

I have several pieces of bamboo that came from the same location in alabama.  do you think that it could possibly all be bad?    Speaking of.. Ill be looking to trade for some more bamboo lol i have osage and snake skins shoot me a pm  ;D :P

Looks like bad Bamboo to me.  Was there any grain run off in that area in the osage ? Dean

If there was there would be very little, I had the grain running most of the length of the bow.

Bad bamboo. Looks like a typical case of bad bamboo. Good bamboo will not have so few splinters when (IF) it breaks. This bamboo is just not strong, it lacks powerfibers - so to speak.
A simple test for a bamboo slat: Take a 1" wide slat, about a foot in length. Bend it 180 degrees by hand. It should not break. It may (or may not) desintegrate with many fibers sticking out, but it should not snap.
