Been there done that, kindasorta. My old original Leatherman PST did not have locking blades, and more than once I had the blade fold up on my right index finger, right where you describe it, altho I never made it all the way to the bone. You now have to try to get the thing to heal, since you will be bending it all the time. Glad you got the bleeding stopped with the super stuff...
