SYR. It's large enough to chop with but small enough to do the little things with and it has the thickness it needs to ignore the possibility of breaking it.
Besides, I have a SOG Powerlock attached to the sheath already with a fire steel and small whetstone packed into a double M-4 mag pouch.
I'm used to the Ka-bar as my all around field knife so this is a step up but roughly the same size. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
