I have had one for a few months now. Other that playing with it some when I first got it, I really don't use it, as it is in my wallet, and it is a backup to the other two knives that I usually carry. 2 1/8 wide by 3 3/8 long by 3/16 thick....I don't know the weight. Seems to be pretty high quality, sharper than he**...... Like I said, I haven't used it, but I feel better knowing that it is there. <br><br>
