Hmmm. I don't know that I'll be recommending the rounded handle model anymore for hard use. I was worried they recessed the liner too far for abuse after seeing those pictures, and guess what pops up in my recommended videos on youtube.....

To be fair, this has been one of my concerns of the RAT after seeing torture tests where they broke in this area, and was why I got rid of my Tenascious too. Realistically it doesn't negate function which is by any means normal. I beat the living piss out of my knives so I'm going to stick to the coffin grip since it has a bit more liner depth.
Too long, didn't read: The coffin grip knife is tougher than the palm swell version, but it will make no difference for 99.9999% of users.
