Carson, two reasons this bow broke...1st-is I narrowed the handle area and that is where it broke and 2nd- I tried to get it to pull to my 26" draw, and that was an inch or two too far. I've used the hold down sinew on a few sinewed backed bows and never had a problem before. Not saying that that wasn't a problem with this bow but I think my other 2 reasons were what made it fail.
I did soak the sinew off of this bow and reused it on another shorty, osage. Like the saying goes...if you ain't breaking them you ain't making them.
