I went through several cycles of thought and questioning before realizing what I really wanted/needed in a knife. I have no need for a blade longer than 3", 2.5" to be honest. I'd thought about a PM2, but realized that I would rarely, if ever, need a blade that long. I honed in on the shorter bladed knives and realized that the Dragonfly was the right blade for me. However, I do not like the FRN, so I got to looking at the G10, which is good, but figured why not go all out. So I requested the ZDP-189 w/Nishijin scales for Christmas, and received it. It fits perfectly in the coin pocket of my jeans and I can count on one hand the number of days I've not had it on me since Christmas.
Should you choose to get a Dragonfly, I feel that you'll be very happy w/your choice.
Compact carry, yet not so small that t feels small in the hand. A wide range of materials for both blade and scales makes for a wide range of prices.
