The Southard has become my most used knife, it is just about perfect in every way. The fit and finish are amazing and it feels like this knife was made for my hand.
This beauty of a knife has just one drawback, and it is the pocket clip. While it isn't horrible by any means, it is just the weakest link of the knife in my opinion. The location of the clip results in a good chunk of the knife sticking out of the pocket. I am less worried about it being visible to people and more worried about it hitting/scratching things (as my spydie clips have done to my car a time or two), and the stock clip left a lot of knife out of the pocket.
The new clip was made by and ebay seller blue4you2010, and I love it. Not only is it titanium, but the color seems to work with the brown g10 very well. The knife rides much lower in the pocket now, and can barely be seen really. I have only had the clip on for a day, so I have not gotten extensive use with it, but I am feeling good about it.
This is also my first customization of a spydie, especially pocket clips. I must say I see myself becoming a pocket clip snob of sorts now.
