I was splitting some real old and twisted oak vertically. I let down on the lever, was steadying with my left, Hit a knot and the log kicked sideways, pinning my fingers against the bar. Released the ram, expecting to find nothing but blood and bones, but lucked out. After the bleeding stopped, everything was still attached. Couldn't move them for about a week however, due to the swelling.
I need to buy a splitter but all I can afford is one of those "Stickler" monsters. They look scary as everything, but I guess it's about the same risk as a table saw with no guard. I guess as long as I do my part it should be somewhat safe. As my hero Homer said, "its like a lottery that rewards stupidity!!"
