Okay - more blade weight means harder to stop. Got it.Actual thickness has little effect regarding safety compared to edge angle. Thicker does usually mean a heavier tool, though, and that means it's harder to stop or control once a blow goes wild.
But, I was trying to figure out what you meant/what the benefit was of having a thin edge as you said in this sentence: "In almost all cases a glancing blow results from striking a target at an angle more shallow than that of the edge (i.e. trying to make a 15 degree approach to the target with a blade that's 20 degrees per side) and is just one of a multitude of reasons why I keep my tools about as thin in the edge as I can within reason."
Thanks again.
