Pro's: Very cool and very classy and unique looking. Very dense all steel knife, I like the heavier weight, suprising for a small knife. Very adequate wide blade with a good amount of cutting edge, it really fits the definition of littel big knife. Very comfortable to hold with several grips and the finger choil lets you choke up on the blade. I want to see more ball locks on more knives, I really like that lock, very out of the way, easy to use, and strong. It is cute, not scary looking at all, and it attracts positive and curious attention because it doesn't look like a knife. Great steel, and great contstruction. I am not sorry at all for buying one.
Cons: for its small size, it is very wide when closed. You might want to put it in a back pocket instead of a front as it will get in the way reaching in for keys or spare change.
One thing I would change: jimping or other texture on the back of the blade for more control. Its small and easy and comfortable to lay your index finger on the back of the knife blade for control...a little extra texture would be a plus.
First impression when I saw one: This is different (said skeptically)
First impression when I held one: SUPRISE! quality, uniqueness, and usefullness, all in one place.
