It would have to depend on your idea of the purpose for carrying the knife.
If it's for general cutting chores including hunting and fishing, as an implement and not a weapon, I wouldn't chose anything with the American idea of a tanto blade. I'd pick a drop-point with no more than four to four and a half inches of blade length--a little less will do for most jobs. I like a sturdy but not too thick blade.
If you're considering your choice to be for self defense, others will have to comment. To me any knife is a tool that can, as an absolute last resort, be used as a defensive weapon. That level of defensive situation is what my gun is for. I won't pick a knife because of its potential in a fight.
But I'm old and don't like getting carved, and carry a Spyderco Endura of SOG Flash II insted of a fixed blade.
