Best of Breed
I have about 10 knives that are in the EDC rotation. I use a CRKT Ken Onion Wrinkle with its big fat round blade when I'm slitting open bag after bag of things like mulch. I use a Spyderco Delica 4 with a combo blade when I am cutting ropes, cord, and heavy string. Over time, though, for everyday carry, I have gravitated more and more to the Wharncliffe style blade, of which I have several. The Leek in general is the most satisfying of them all, and the Carbon Fiber in specific is for me ideal. I first bought a 1660SW Blue, and it is very pretty. I found, though, that it felt a little heavy in my pocket, so I tried out the 1660CF with its CPM154 blade. For me, the blade shape is perfection - the tip shape works great for precision cutting and trimming, while the blade is still strong enough for basic cutting and slicing work. The lighter weight makes it a delight to carry, and the improved steel holds an edge longer and, because of the blade shape, is not all that difficult to keep sharp. Additionally, all of the metal-handled Leeks are a little slippery. The carbon fiber is not. The one fly in the ointment is the stupid blade lock. If you ever needed to get at your knife because of a threat, you can be sure that it will have locked itself in place without your knowledge and you'll go down while you are fiddling with it. Most of us, I realize, are not using our pocket knives for self defense, but even in daily use the lock is annoying; I can't see why anyone would need such a thing. If you can overlook this (or disable it), this knife is, for my use, best of breed. I love the thing.
