I love mine. One of my favorite EDC blades. That said, no knife is perfect. Here's a breakdown of pros and cons (in my opinion)
Pros:
CTS-204P steel is probably my favorite steel. Great all around steel that holds an edge a very long time with good corrosion resistance
The look. This is a great looking design. I love almost everything about this knife, from the shape of the scales and blade to the contrasting Titanium and G-10 scales to the G-10 liner overtravel stop
Blade shape. Not only does it look great, but the shallow belly and tall grind combined with the blade thickness make it a great overall cutter that should be relatively easy to sharpen (at least as 204P goes)
Weight and size. I could do for a smaller version (I typically like knives around a 3 inch blade), but a little extra size in a flipper feels pretty good. The weight seems to be perfect for the blade size too. Not the lightest, but not too heavy either, just enough to feel solid
Overall ergonomics. The ergos are much better than they look. You give up something for the sleek look of the straighter handles, but the ergonomics of this knife are still very good
Flipping action. The action of this knife is one of the smoothest, most perfectly opening flippers I've ever used (I prefer flippers that open with authority when you want them, but still give you enough control for a more subdued opening when you want it). It's not the fastest, but always opens completely and very smooth
G-10 side provides plenty of traction. It always feels secure in the hand
Cons:
Although overall ergos are very good, I wish it had more of a thumb ramp. It's the only place that the ergonomics seem to be missing anything (although a thumb ramp would totally change the look of the knife, sacrifices must be made in one area or another)
Pocket clip doesn't match the Titanium scale. That's just the way it was designed. Not a big deal, I just wish it matched
Lacks real jimping for the thumb. A little jimping on the flipper would be nice too
The G-10 around the spyderhole is ground out in a deep hollow shape (I'm not sure how to describe it). You can't feel it when you hold it, but it doesn't look as nice. I would have preferred it to be ground flat
That is everything I dislike about the knife, along with some of the things I like most about it. Overall the Southard is a great EDC knife. It does everything I ask it to do and looks and performs great while doing so. I don't see myself ever getting rid of mine
