SteelDriver said:He didn't continue because the knife broke. Please go back and read what Nutnfancy wrote (quoted in my post above). The technique requires the user to maintain downward pressure on the handle during batoning. He did not run out of blade, as "Most of the hits were on the front of the blade protruding from the log...." If the blade is protruding from the log, how can he run out of blade to hit? I don't think the handle just happened to fall off, either. It seems from Nutnfancy's picture and account that the RS was already used to split some of the log and that a final blow was required to break the knife.
Disregard NutnFancy's description for a moment and look at the knife. While much of the forward part is visible (protruding?) from the front, the knife spine is level with the rear of the log along it's entire length (except near the tang). The knife is essentially completely embedded. Put yourself at the scene and baton away. How much farther can you drive it? Striking the knife anywhere along the spine means striking the log also--thus, not effect. At some point, the most obvious scenario becomes that of striking the handle. Two choices there: 1. tap the handle from the bottom in an attempt to remove the knife and try again with a little less aggressive bite at the apple, or 2: keep whaling away.
And the log only gets thicker the farther down you go.
