Mac got it right. Very thin grind, high hardness steel, a good knot in the wood and major force = chipped out. You can conclude the Grip won't compete with a fixed blade for batoning and you'd be right. Sorry it happened.

An alternative skill that might be interesting to try is cutting/shaping wedges to do the splitting while batoning. If you master wedges you can split darn near anything with a small knife! <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
