Depends on how large a set of hands you have, as to which size to get.
I've heard a lot of folks say the small was too small for them and others say the large was too large for them, a fellow here at work, Greenie on the forums, insists that Chris Reeve Knives needs to come up with a knife that lies between these two sizes, maybe they will?
I like all three sizes that they put out, the Small Sebenza being the optimum size and still strong enough for about any job.
Haven't held any of the Dozier folders but the D2 steel is pretty good stuff.
I've got it on pretty good account though, that a Talonite (R) folder would be the last knife you need to buy, as this source told me, since he has the Carnivour in Talonite, it has become his daily carry, barr none!
Now I can't wait till I receive my Talontie Carnivour sometime next month I would hope and I'll post my finds and see if it makes the others take a back seat!
Good luck on your search! I sort of cheat in that I carry multiple knives, but the M2 AFCK rides in my front pocket everyday, no matter what knife I choose to wear on the belt, so the M2 is taking more of the abuse, tough knife, so don't rule them out!
