my beaters are a Camillus pilot survival knife and Ontario RTAK.
Everyone's gripe with the Camillus is the tip; but I've used this knife hard, thrown it into numerous trees, and it still has a tip... so I don't know how people are breaking the tips off of these things.
The RTAK is just plain fun, and nearly perfectly balanced to throw (but I've only done that a few times).
I've given both a utility edge, though the RTAK would shave hair out of the box

. But I deemed that kind of edge inappropriate for that kind of knife and reprofiled it.
I'm thinking about getting a RAT-7 because my Ka-Bar is just too pretty to abuse.
Folder... just about all of my EDC folders are in the beater category. My current EDC rotation: Buck 301, PE FRN Endura, Camillus Heat, large Sebenza.
I haven't had the 301 long enough to do any serious damange. The Endura is relatively new too, but has done everything I could ever want it to do and more. The Heat has the black coating and the only place it's wearing is on the flipper where it hits as I walk past and into things. I've had the Sebenza for a few years and it attained beater status when the blade caught a big staple in a box and left a scratch along 3/4 of the blade. But each one of those knives I know can handle everything I need them to.
The only folder that I carry that I don't consider a beater is my Vic Soldier, because I carry that solely for food prep and wouldn't cut what I cut with the others with it.
