I normally carry three knives, and each have their specific purpose. As a righty, I carry either the 0561, Strider SMF, Strider SnG, Lion Steel SR1 or large Sebenza 25 in the RH strong pocket mainly for defensive purposes. I keep these knives razor sharp, and never have to re-sharpen then because they are never used (and hopefully never will be). In my left pocket, I always carry a Benchmade Griptillian for EDC cutting tasks, box opening, etc. I carry a Carter Cutlery neck knife as a general backup to all of the above. When working in the woods or around the property, strong side pocket knife is usually replaced with a Survive GSO 4.1 fixed blade on my belt, or a Survive GSO 5.1.
I find that the ZT 0561 is an exceptional value, beefy enough to do hard chores, and ergonomic enough to be a formidable force in a fight. It is a little large, but I do not mind large folders for the purpose that I carry them. As far as large folders are concerned, the Strider SMF is much lighter than the ZT 0561, but it also costs much more money. For the price, the 0561 is probably the best value knife that I own. But I must qualify this with the purpose that I carry it, defense. None of my defense knives are efficient cutters (except for the Sebenza) as they all have thick blades. These knives will double for a survival knife if they have to, so I want beefy to thump on in case I have to. I am not saying that they are good survival knives, but they can double for one in a pinch. I am completely satisfied with my ZT, and it is in my strong side rotation frequently.
