the edge on griptilians are very thin, they have high hollow grinds that are very thin
he was not cutting wood he said he was batoning it, I hope you know the difference
when batoning you compress the blade edge and because the blade edge is so thin the pressure does not have enough room too disperse
that combined with the blade that is hardened to about 62rc for edge holding and you get edge falure
griptilians are made for sliceing not batoning
you cannot expect a knife for edc and self defense to do work like a fixed blade
they are different animals
