OUCH! I had one roll oddly off the sawbuck last week as well and catch me in the shin. Doesn't sound like it was as painful as yours though! Now I take a step back when the saw clears the cut instead of standing there admiring my handiwork.
As "Holy Grail" quotes go, it was only a "flesh wound" but when something "locust tough" connects with bone on the thin ankle skin, kinda makes ya either puke a little in yer mouth, or pizz a little squirt!!!!
OUCH I know that hurt . Today I looked and saw blood running down my arm , didn't know how I did it , no big deal though
